Sir Keir Starmer has vowed not to cross the “red line” of bringing back freedom of movement with the EU as he accused allies of Rishi Sunak of wanting to renegotiate Brexit.
The Labour leader was ruling out a Swiss-style deal with Brussels that would allow access to the single market after a report suggested the Government was considering the move.
His warning that “ripping up the Brexit deal would lead to years more wrangling and arguing” appeared to be an attempt to outflank the Conservatives on Brexit.
The Prime Minister and Chancellor Jeremy Hunt have been under pressure from Tory Eurosceptics after the Sunday Times suggested senior Government figures were considering a Swiss-style deal.
The Labour leader told the Mail on Sunday: “A Swiss deal simply wouldn’t work for Britain. We’ll have a stronger trading relationship and we’ll reduce red tape for British business – but freedom of movement is a red line for me.
“It was part of the deal of being in the EU but since we left I’ve been clear it won’t come back under my government.”
He said he wants to “get on with what the country wants” instead of trying to broker a fresh trade agreement with Brussels.
“Ripping up the Brexit deal would lead to years more wrangling and arguing, when we should be facing the future,” he said.
“I’m worried that there are senior members of Rishi Sunak’s Government who don’t seem to understand that and are going round saying they want to open up the Brexit debate again.”
He said he will “always seek a close relationship with our neighbours” but reiterated that would not “be about the single market, the customs union or freedom of movement”.
This week he rejected the Office for Budget Responsibility’s forecast that Brexit will cause a 4% reduction in GDP, a measure of national income.
Mr Hunt insisted to MPs he does not support Britain rejoining the single market of frictionless trade.
The Chancellor issued a carefully worded denial that he was behind suggestions that ministers are considering a Swiss-style relationship with the EU, but repeatedly did not deny the Treasury was behind the briefing.
Meanwhile, exports to Japan fell following the first major trade deal after Brexit, signed with Tokyo by Liz Truss while she was trade secretary.
Department of International Trade figures put UK exports to Japan at £11.9 billion in 2022, a decrease of £438 million compared with the year before.
Shadow international trade secretary Nick Thomas-Symonds said: “The Government’s trade policy is in crisis and these failures are making the Tory economic chaos even worse.
“Falling trade with Japan shows that their trade deals are not delivering – and it’s British businesses and working people who are paying the price.”
