Labour leader Jeremy Corbyn has Brexit woes of his own.

Four million people are thinking of switching to Labour, says a poll of 10,000 voters published exclusively in the Sunday Mirror today.

That would make him PM – but to win them over he must be clearer on his Brexit position.

Nearly seven in 10 want to stay in the EU and 59% back a second referendum, says the YouGov superpoll for campaigners People’s Vote.

But less than a quarter of the group say they know what Labour stands for, while half of Tory voters are clear on their party’s position.

It doesn’t help that Shadow International Trade Secretary Barry Gardiner last week warned of civil disobedience if there was another referendum – while Labour’s Brexit chief Sir Keir Starmer said the party had not ruled one out.

Pollster Peter Kellner said: “These people don’t support Labour now. But they ‘would seriously’ or ‘might’ consider voting Labour at the next General Election.”
