Nigel Farage has challenged Jeremy Corbyn to a debate before the European elections as he said he wanted to “dig in” to Labour voters who felt let down by the party’s “confusing” Brexit stance.

The leader of The Brexit Party said he would be targeting Leave-voting Labour heartlands in the run up to May 23 and that if his strategy was successful “we can surprise even ourselves how well we do”.

Meanwhile, Mr Farage warned Theresa May against striking a softer Brexit compromise deal with Mr Corbyn as he said it would represent a “final betrayal” for Leave voters.

A recent YouGov poll found 30 per cent of voters intend to back The Brexit Party at the European Parliament elections, far ahead of Labour on 21 per cent and the Conservatives on 13 per cent.
