UK Government Plans Bill Allowing Ministers to Adopt EU Rules Without Full Parliamentary Votes

The Starmer government is preparing to introduce legislation that would grant ministers the power to align UK law with EU regulations in selected policy areas — without requiring a full parliamentary vote for each rule adopted. The proposed bill, expected to be laid before Parliament in late 2026, is the legislative vehicle for implementing the UK-EU Sanitary and Phytosanitary (SPS) agreement and the broader reset of relations agreed at the May 2025 summit [1]. It would mark the most significant transfer of regulatory authority from Parliament to the executive since the EU Withdrawal Act of 2018 — and, critics argue, the most consequential use of so-called Henry VIII powers in modern British history.

The Architecture of the Bill

At the centre of the proposal is a mechanism for "dynamic alignment" — a commitment by the UK to adopt, on an ongoing basis, EU regulations in specified sectors as they are updated in Brussels [2]. Unlike the pre-Brexit era, when the UK had a vote and a veto in EU institutions, this arrangement would make Britain a rule-taker: bound to implement regulations it had no formal role in shaping.

The government published a written statement on 9 March 2026 outlining the scope of the SPS agreement, which would cover food and feed safety, animal and plant health, pesticide and biocide regulation, organic standards, nutrition labelling, and key agrifood marketing and compositional standards [3]. The Department for Environment, Food and Rural Affairs confirmed that the UK would align with this body of EU legislation dynamically, meaning new EU rules would be transposed into UK law as they emerged [3].

Separately, the Product Regulation and Metrology Act — which received Royal Assent in July 2025 — already grants ministers broad delegated powers to mirror EU product regulations through statutory instruments [4]. The House of Lords Constitution Committee warned that these powers were "very broadly framed and could facilitate the making of law that goes beyond the updating of existing rules to involve the making of new policy" [5]. The government subsequently amended the bill to require more regulations to be subject to the affirmative procedure (requiring a vote in both Houses) rather than the negative procedure (deemed approved unless a motion to annul is tabled within 40 days), and removed some of the most expansive Henry VIII clauses [4].

The policy areas under negotiation extend beyond food. The May 2025 summit joint statement committed both sides to work toward linking UK and EU emissions trading systems, mutual recognition of professional qualifications, and electricity market integration [1]. Financial services remain a conspicuous absence — a sector where the UK and EU are competitors rather than partners, and where the UK has deliberately pursued regulatory divergence [6].

The Scale of Secondary Legislation

The volume of statutory instruments — the legal mechanism through which ministers would adopt EU rules — has been elevated since Brexit. In the five years before the 2016 referendum, the UK laid an average of approximately 2,917 statutory instruments per year. In the years following the referendum, that figure rose sharply: 3,652 in 2019, 3,789 in 2020, and remained above 3,000 annually through 2024 [7].

A significant share of these post-Brexit instruments were directly related to untangling EU law from the UK statute book. The European Union (Withdrawal) Act 2018 alone conferred powers on ministers to create statutory instruments addressing legal issues caused by Brexit [8]. The Retained EU Law (Revocation and Reform) Act 2023 gave ministers further power to decide the future of thousands of pieces of inherited EU legislation — a process the House of Lords Delegated Powers and Regulatory Reform Committee described as using Henry VIII powers "on steroids" [9].

Adding a new stream of instruments — this time to re-align with EU rules — would increase this volume further, at a time when parliamentary capacity to scrutinise secondary legislation is already stretched.

The Cost of Divergence: The Economic Case for Alignment

Supporters of the bill ground their argument in measurable economic harm. The Office for Budget Responsibility has maintained since 2020 that Brexit will reduce UK GDP by 4% over 15 years relative to remaining in the EU, primarily through reduced trade intensity [10]. The OBR confirmed in March 2024 that this trajectory was "on track," despite criticism from Brexit supporters that the estimate is overly pessimistic [10].

The trade data supports the OBR's assessment. UK exports and imports with the EU fell by 17% and 23% respectively between 2021 and 2023 when measured annually [11]. The number of UK businesses exporting solely to the EU dropped 19% in a single year, from 17,800 in 2023 to 14,300 in 2024 [11]. The EU's share of total UK trade has fallen from 53.4% in 2016 to approximately 41% in 2024, a decline only partially explained by trade diversification [12].

For specific sectors, the costs are concrete. The UK chemicals industry faces an estimated £1 billion in duplicated compliance costs from operating under both UK REACH and EU REACH regulatory systems [13]. Export Health Certificates for food products cost up to £200 per consignment — a cost the SPS agreement would eliminate [3]. Around half of UK exporting firms and two-thirds of importing firms reported additional costs associated with post-Brexit regulatory changes in an ONS survey from early 2024 [10].

The steelman case for the bill is that the status quo — in which businesses face dual compliance burdens, border checks, and mounting paperwork — is itself a form of democratic failure. If regulatory divergence costs consumers and firms measurable sums annually while delivering no corresponding sovereign benefit, then re-alignment through streamlined legislation restores rather than undermines accountability.

Henry VIII Powers and Constitutional Precedent

A Henry VIII clause — named after the king's preference for governing by royal proclamation rather than through Parliament — allows ministers to amend or repeal provisions in an Act of Parliament using secondary legislation [14]. These clauses are not new, but their scope in the Brexit and post-Brexit era has been unprecedented.

The EU (Withdrawal) Act 2018 conferred on ministers "wider Henry VIII powers than had ever been seen before," according to the House of Lords Constitution Committee [15]. The Retained EU Law Act extended these by allowing ministers to modify thousands of pieces of retained EU law through statutory instruments, with minimal parliamentary scrutiny [9].

The new alignment bill would add a different dimension. Rather than granting ministers power to remove EU-derived rules from UK law, it would authorise them to adopt evolving EU rules — creating an open-ended commitment to transpose regulations from a body in which the UK has no legislative seat. The House of Lords European Affairs Committee has called on the government to "facilitate parliamentary scrutiny of the new UK-EU agreements" and to clarify how the system of dynamic alignment will operate, with particular emphasis on Parliament's role [16].

The Hansard Society, a parliamentary watchdog, has warned that the government lacks a dedicated Commons committee to scrutinise the UK-EU relationship, unlike the pre-Brexit European Scrutiny Committee that reviewed EU legislation before it applied to Britain [17].

Deliberate Divergences and Who Lobbied for Them

Not all post-Brexit regulatory divergence was accidental or unwanted. Several divergences were pursued as deliberate policy choices by the previous Conservative government, sometimes at the urging of specific industry groups.

On chemicals regulation, the creation of UK REACH as a separate system from EU REACH was framed as an opportunity for "regulatory sovereignty." Yet the Chemical Business Association has campaigned since December 2021 for the government to reverse course, arguing that "the uncertainty around UK REACH continues to stifle investment" [13]. The UK's Environment Agency has been unable to keep pace with EU regulatory developments, lacking the capacity, expertise, and resources of the European Chemicals Agency [13].

On precision breeding (gene editing in agriculture), the UK passed the Genetic Technology (Precision Breeding) Act 2023, deliberately diverging from the EU's more restrictive rules. The National Farmers' Union and biotech companies supported this divergence. The Commons EFRA Committee has recommended that precision breeding be exempt from any SPS dynamic alignment requirement, preserving what it calls the UK's "regulatory innovation capacity" [18].

On product standards and CE/UKCA marking, the government repeatedly delayed requiring businesses to switch from the EU's CE mark to the UK's UKCA mark — effectively acknowledging that divergence imposed costs without clear benefit. The Product Regulation and Metrology Act now gives ministers power to recognise EU standards voluntarily [4].

The Devolution Question

SPS policy is devolved — Scotland, Wales, and Northern Ireland all have competence over food standards and agricultural regulation within their jurisdictions. But the negotiation of international agreements is reserved to the UK government. This creates what academics have called a "structural tension" in the SPS agreement [19].

A future common SPS area would require "legislative and administrative adjustments across all four nations," with the EFRA Committee calling for "meaningful and formalised engagement with the devolved administrations" [18]. The record on this front is poor. The Scottish Parliament withheld consent for the EU Withdrawal Act 2018, and all three devolved legislatures refused consent for the EU Withdrawal Agreement Act 2020. Both Acts passed regardless [20].

The Sewel Convention — the principle that Westminster will "not normally" legislate on devolved matters without the consent of the relevant devolved legislature — is not legally binding. The Supreme Court confirmed in the Miller I case that it is a political convention, binding "in honour only" [20]. If the alignment bill creates powers for UK ministers to transpose EU regulations into areas of devolved competence without the consent of Holyrood, the Senedd, or Stormont, it would intensify existing tensions and could trigger legal challenge — though the courts have shown reluctance to enforce the Sewel Convention judicially.

The Windsor Framework, which governs Northern Ireland's post-Brexit regulatory position, already requires Northern Ireland to dynamically align with EU single market rules for goods. An SPS agreement that brings Great Britain into alignment with the same rules could reduce the regulatory border in the Irish Sea — a goal welcomed by many in Northern Ireland but viewed with suspicion by unionists who see it as further evidence of constitutional drift.

How Norway and Switzerland Handle Rule Adoption

The UK is not the first non-EU country to grapple with how to adopt EU rules while maintaining democratic oversight. Norway, as a member of the European Economic Area, is bound by approximately 5,000 EU laws — roughly 21% of all EU legislation in force [21]. New EEA-relevant EU legislation is adopted through the EEA Joint Committee and, where it involves "significant new obligations," must be approved by the Norwegian Storting (parliament). In practice, 92% of such laws were approved unanimously between 1992 and 2011 [21].

However, Norway's arrangement has been criticised for a growing "democratic deficit." EFTA countries have no representation in EU institutions and only indirect influence on legislation that affects them. The 2024 Norwegian EEA Review concluded that "the lack of political influence is a growing problem" that has expanded quantitatively even if the qualitative nature of the deficit has not changed [22].

Switzerland operates under a system of bilateral agreements with the EU rather than a treaty-based obligation to adopt EU rules. Swiss alignment is selective and sector-by-sector, with stronger domestic democratic checks — including the possibility of a popular referendum on any new agreement.

The UK bill, as described so far, appears to offer weaker parliamentary scrutiny than Norway's system (which at least requires Storting approval for significant measures) and weaker democratic safeguards than Switzerland's (which preserves the option of referendum). The use of the negative procedure for statutory instruments — where regulations take effect unless Parliament actively objects — is a lower bar than either comparator.

The Opposition: Back Door to Brussels?

Reform UK leader Nigel Farage has argued that the reset plans agreed in May 2025 push the UK "back into the orbit of Brussels, giving away vast amounts of our sovereignty for very little in return" [23]. Farage has said that dynamic alignment to EU rules "makes voting at general elections irrelevant" because regulations would be set by EU institutions rather than the UK Parliament [23].

Robert Jenrick, who defected from the Conservatives to Reform UK in January 2026, delivered a broad critique of both major parties upon joining, declaring that Labour and the Conservatives are "rotten" and "no longer fit for purpose" [24]. The Conservatives under Kemi Badenoch have said they would oppose new UK-EU agreements that involve an obligation to align with EU laws or give jurisdiction to the Court of Justice of the EU, and that a future Conservative government would not be bound by a "bad Labour deal" [23].

The specific safeguards that Eurosceptic critics demand include: sunset clauses requiring periodic parliamentary reauthorisation of any alignment powers; a parliamentary override mechanism allowing either House to block specific EU rules from being transposed; limitations on the scope of alignment to exclude areas of deliberate UK policy divergence (such as precision breeding); and a commitment that no alignment agreement would grant the European Court of Justice any role in UK legal proceedings [23][18].

The Government's Response

The government's position is that the bill represents "the sovereign choice to mirror or diverge" from EU rules [4]. Ministers argue that the current system — where businesses face mounting compliance costs, border friction, and regulatory uncertainty — is itself a failure of democratic governance, because it imposes costs on constituents without any corresponding legislative mandate.

The Institute for Government noted that the government "will have its work cut out to convert words in 2025 into concrete actions in 2026" [25]. The EFRA Committee recommended transition periods of at least 24 months for sectors affected by new SPS obligations, along with adequate resourcing for the Food Standards Agency, Food Standards Scotland, and port health authorities [18].

Whether the bill provides sufficient parliamentary scrutiny will depend on its final text. The critical variables are: whether alignment regulations require the affirmative procedure (an active vote) or the negative procedure (deemed approved by default); whether there is a dedicated parliamentary committee to scrutinise incoming EU rules; whether the devolved governments have a formal role in decisions affecting devolved competence; and whether the bill includes a mechanism for the UK to refuse specific EU rules while remaining within the broader agreement.

What Remains Unclear

Several questions remain unanswered. The government has not published the bill text, and the scope of dynamic alignment beyond SPS and product standards has not been formally confirmed. The role of the European Court of Justice — a political lightning rod since 2016 — in any dispute resolution mechanism is under negotiation. The financial services sector remains outside the current proposals, but pressure from the City of London for mutual recognition of regulatory standards could bring it into scope in future agreements.

The economic case for alignment is strong in aggregate but contested in specific sectors where the UK has pursued deliberate divergence. The constitutional case is genuinely two-sided: the bill concentrates power in the executive, but the status quo leaves businesses and consumers bearing the costs of a regulatory limbo that Parliament has done little to resolve.

The legislation, when it arrives, will test whether the UK's post-Brexit settlement can sustain a middle path between full regulatory independence and the practical benefits of harmonisation with its largest trading partner — and whether Parliament is willing to accept a reduced role in that process.
