Sadiq Khan Says Brexit Result Could Be 'Trumped' By Labour Manifesto Pledge On Remaining In EU

He said he's an 'optimist' about the UK staying in the EU.

Brexit could be halted if Labour used its next general election manifesto to commit to not leaving the EU, or holding a second referendum, Sadiq Khan has said.

In a pointed intervention after days of conflicting signals on Brexit from senior Labour figures, the Mayor of London insisted he was an “optimist” about the chances of the UK staying in the EU, the Press Association reported.

Khan said Labour needed to be clear on its stance, telling the Guardian: “For it to have credibility with the British public, there would have to be a Labour manifesto offer, because the public would say, not unreasonably, ‘Hold on a sec, we voted to leave and you’re now sticking two fingers up at us’.

“You’d have to spell out, in black and white, what we’d do if we won the general election.

“What could trump the referendum result is us having a manifesto offer saying we would not leave the EU, or we would have a second referendum.”

Labour has been accused of facing in different directions over Brexit after leader Jeremy Corbyn insisted the party wanted the UK to leave the EU single market, before shadow Brexit secretary Sir Keir Starmer said nothing was off the table.

Labour’s manifesto said the party “accepts the referendum result”.

Khan’s remarks came after Chancellor Philip Hammond said a post-Brexit transitional arrangement could last for three years after the UK’s planned withdrawal in March 2019.

Hammond said “many things will look similar” on the first day after leaving the bloc.

Sources close to Foreign Secretary Boris Johnson told the Press Association he was working closely with the Chancellor to take the UK out of the EU.
