Labour should go into the next general election with a pledge to rejoin the European Union,Sir Sadiq Khan has said.
The Mayor of London argued that Brexit has caused massive damage to the British economy in the six years since the UK left the bloc.
He has previously advocated Labour reentering the customs union and single market with the EU,but his new comments go a step further.
Speaking to Italian newspaper La Repubblica,Khan said: ‘We should,as a Labour Party,fight the next general election with a clear manifesto commitment,a vote for Labour means we would rejoin the European Union. I think it’s inevitable.’
The move could be made without holding a second referendum on the issue,he suggested.
Khan’s intervention comes days after Chancellor Rachel Reeves counted a closer relationship with the EU as one of her three biggest opportunities for growth.
Speaking at the annual Mais Lecture on Tuesday,she said: ‘Britain’s future prosperity will not be built in isolation,but through partnerships with those who share our interests,share our values,and share our ambitions.
‘And no partnership is more important than that between the UK and our European neighbours.’

However,Labour ruled out any return to the customs union,single market,or freedom of movement in its 2024 election manifesto,saying it would avoid ‘reopening the divisions of the past’.
Downing Street has since described these as its ‘red lines’ on the EU – even after Deputy Prime Minister David Lammy suggested on a podcast last December that his party’s policy on the bloc could change.
In an appearance on The News Agents,Lammy said it was ‘self-evident’ that the economy had been damaged by Brexit and ‘created serious friction’.
When asked about rejoining a customs union,he said: ‘That’s not currently our policy,that’s not currently where we are.’

Responding to those comments at the time,a No 10 spokesman pointed to individual trade deals the UK had made with the US and India which would not have been possible within the EU.
But a source close to Khan told Metro the Mayor believes this argument was undermined by Donald Trump’s decision to start the war in Iran and his capricious use of punitive tariffs.
The President’s behaviour demonstrated the US is ‘not a reliable partner’,they said.
In her lecture on Tuesday,Reeves said the trade deals were ‘extremely welcome and beneficial’ but were not a cure-all for the UK economy.
She said: ‘No trade deal with any individual nation can outweigh the importance of our relationship to a bloc with which we share a land border,with which our supply chains are closely intertwined,and it accounts for almost half our trade.’
