The loudest promise of the Brexit campaign was parliamentary sovereignty — the idea that Britain’s elected representatives, not bureaucrats in Brussels, would decide the laws governing the United Kingdom. A decade later, Prime Minister Keir Starmer is preparing legislation that would allow the UK government to adopt EU single market rules without MPs voting on them at all.

The mechanism is a procedural one, buried in the fine print of legislation expected later this year. Under what officials call “dynamic alignment,” the UK would automatically mirror new European regulations in areas where trade deals have already been signed — food standards, animal and plant health, and potentially other sectors. When Brussels updates a rule, Westminster would follow suit through secondary legislation, a process that typically cannot be amended and is usually rubber-stamped without a vote.

For a government that has explicitly ruled out rejoining the EU single market or customs union, it is a strikingly close approximation of membership — at least in regulatory terms.

The Deal and the Numbers

The legislation is designed to accompany a broader UK-EU trade package, including a “food and drink” agreement that the government values at £5.1 billion a year. A Labour source told the BBC the measure would “lower costs for businesses and get rid of the Brexit paperwork tax that adds to the cost of the weekly shop.”

The UK and EU are currently negotiating several deals, building on an agreement struck last May covering fishing rights, trade, defence, and energy. Starmer has said this year’s upcoming UK-EU summit will be “more ambitious” and “will not just ratify existing commitments made at last year’s summit.”

A government spokesperson insisted that “the bill will go through parliament in the normal way,” noting that “any new treaties or deals with the EU will also face parliamentary scrutiny, and Parliament will have a role in approving new EU laws required under those deals via secondary legislation.”

But “secondary legislation” is precisely where the controversy lies. Unlike primary legislation, statutory instruments are subject to minimal parliamentary debate and generally cannot be amended. MPs are presented with a take-it-or-leave-it choice, and in practice, the vast majority pass without any vote at all.

The Sovereignty Irony

The political charge is immediate. The Brexit referendum was won on the argument that the UK had lost control of its laws to EU institutions. “Take back control” was not merely a slogan; it was a constitutional argument — that only the British Parliament, accountable to British voters, should legislate for the British people.

Now, Conservative shadow business secretary Andrew Griffith argues the opposite is happening: parliament is being “reduced to a spectator while Brussels sets the terms.” Nigel Farage, leader of Reform UK, went further, calling the plans “a backdoor attempt to drag Britain back under European Union control” and vowing to oppose the legislation “every step of the way.”

Even voices sympathetic to closer EU ties have raised concerns. Liberal Democrat MP Munira Wilson told the BBC’s Westminster Hour: “We need a closer relationship with Europe, but we also need parliamentary democracy.”

A Labour source framed the approach differently: “We’re making a sovereign choice to agree deals to reduce trade barriers — where Parliament gets to have a say.”

The framing is technically defensible. Parliament would vote on the enabling legislation, and individual rules would pass through a parliamentary process. But critics argue that once the framework is in place, individual MPs would have no meaningful opportunity to shape, amend, or reject specific EU regulations as they arrive.

What This Signals

The legislation represents something broader than a technical trade measure. It signals the quiet realignment of British politics in the post-Brexit era. Having left the EU, the UK is now negotiating its way back toward regulatory alignment — not through a dramatic reversal, but through incremental, largely technical agreements that attract less public attention than a referendum ever did.

For businesses, particularly in the food and agriculture sectors, dynamic alignment has clear appeal. Divergent regulations create friction, costs, and delays at borders that did not exist before Brexit. The government’s £5.1 billion figure, if accurate, represents real economic weight.

But the democratic question remains unresolved. If the purpose of Brexit was to restore full legislative control to Westminster, then automatically adopting rules written in Brussels — however practical — sits in direct tension with that principle. Starmer’s government is betting that voters care more about grocery prices than about the procedural mechanics of statutory instruments.

They may be right. But the fact that this debate is happening at all — under a Labour prime minister, using tools once denounced by Brexiteers as evidence of EU overreach — marks a significant shift in the trajectory of British politics since 2016.
