“We should rejoin the customs union in this parliament … we should rejoin the single market. We should try to do this during this parliament,” he told the newspaper.
“And then we should, as the Labor Party, fight the next general election with the clear commitment of a manifesto, a vote for Labor means we will rejoin the European Union.”
Khan, whose home city of London voted strongly to remain in the European Union in 2016, said the damage done by Brexit had made Britain’s reunification with the union “inevitable.”
But when asked about the mayor’s comments on Thursday, the prime minister’s spokesman told a regular press conference in Westminster: “The government’s red lines are on the notice stand.”
The spokesman added that the manifesto was valid for the “entire term of parliament” and when pressed on future plans said: “We will not write a manifesto for the next election here.”
Khan is the main figure in the Labor party so far to discuss the topic of Britain rejoining the bloc – while the issue is still considered politicized in Westminster.
