Former European Union Brexit chief negotiator Michel Barnier has cautioned that the United Kingdom will not be permitted to "cherry pick" elements of the EU single market, following statements by Prime Minister Andy Burnham indicating a desire to seek closer economic alignment with Europe.
Speaking during a Sunday broadcast interview, Barnier stressed that EU member states would firmly demand that Britain reinstate core conditions, including the free movement of people, to regain single market access. Rejoining the internal market, which facilitates borderless trade in goods, has been listed by the prime minister as one of several avenues under consideration to reshape relations nearly six years after the UK departed the bloc.
Barnier emphasized that European nations will not accommodate a "single market à la carte" approach where the UK selects preferred terms. He noted that full single market access mandates total compliance with EU regulations governing the seamless movement of goods, services, capital, and people—collectively known within bloc institutions as the "four freedoms."
"There will be no possibility to have one freedom and not the other," Barnier said. "The four freedoms are clearly the four conditions to be inside a single market." He added that while the European "door is open" for Britain to rejoin as a full EU member state, any return to the single market requires strict adherence to identical standards applied to existing members.
Since assuming the premiership in July, Burnham has indicated that he could position the Labour Party toward securing a significantly deeper long-term relationship with Europe, including potential full membership re-application, though he has ruled out implementing major structural shifts prior to the next general election.
The free movement of people, which grants EU citizens the right to reside and work across member countries without requiring visas, served as a core battleground during the 2016 Brexit referendum. Burnham's immediate predecessor, Sir Keir Starmer, explicitly ruled out reinstating free movement within Labour’s 2024 election manifesto. Re-opening debate on the issue would establish a sharp political dividing line against the Conservative Party and Reform UK in future elections.
Burnham recently stated in an interview that he would not restore free movement without putting the matter to a national referendum. His remarks prompted Downing Street to clarify that the prime minister is not actively advocating for free movement's return at the present time. Burnham previously stated his intent to outline "different options" regarding European policy at an upcoming summit in Brussels later this month, aimed at establishing public consensus on a renewed relationship.
Barnier also ruled out any possibility of restoring the UK's historical financial rebate. Originally negotiated in 1985 to reduce Britain's net payments toward the EU's annual budget, the mechanism is no longer viable, according to Barnier. He noted that the UK's departure created an entirely "new situation," rendering any renewed rebate "off the table."
During the interview, Barnier drew comparisons between Reform UK leader Nigel Farage and French politician Marine Le Pen. "We have our own Farage. It is Mrs Le Pen," Barnier remarked. "The same populism, the same lies, the same false promises."
When pressed to detail his allegations of deception, Barnier pointed directly to campaign claims concerning European contribution figures. "For instance, when Mr Farage and Mr Johnson promised the UK people to get back [£350] million per week, it was not true, it was not possible. It was a lie," Barnier stated.
The assertion refers to the 2016 Vote Leave campaign—in which Boris Johnson played a prominent role—which displayed a slogan on its campaign bus claiming Britain sent £350m weekly to the EU and urging, "Let's fund our NHS instead." In 2017, Johnson defended the figure, stating that "once we have settled our accounts, we will take back control of roughly £350m per week. It would be a fine thing as many of us have pointed out if a lot of that money went on the NHS."
Critics have long countered that the £350m figure represented a gross contribution estimate that failed to account for Britain’s £75m weekly rebate or EU investments returned to the UK. Johnson later maintained his stance, arguing the figure reflected gross payments and was an underestimate given projected budget increases. In his 2024 memoirs, Johnson argued that EU spending in Britain lacked democratic oversight by the public, writing that "even if the net figure was only £175m, that was still a hell of a lot of money."
Farage, who led the separate Leave UK movement and was not affiliated with Vote Leave or the £350m bus campaign, strongly rejected Barnier’s comments. "It is the same old Barnier – arrogant, out of touch and a bully," Farage responded. "He vindicates our decision to leave every time he opens his mouth."
Barnier, who headed the EU negotiating team throughout Brexit talks between 2016 and 2021, also briefly served a three-month tenure as Prime Minister of France in 2024.
