Jeremy Corbyn came under renewed criticism last night after he was seen being held back by aides as he appeared to lunge at a reporter during a rally in his constituency.

The confrontation came as it was revealed that Mr Corbyn’s aides are deliberately refusing to allow him to speak to other MPs.

Pressure on the Labour leader to resign intensified after an independent poll found that most members of Unite, one of his biggest union supporters and a major Labour donor, want him to quit before the next election.

The latest row happened at a community event at a “Say No to Hate Crime” rally organised by the local Labour party at Highbury Fields in his Islington constituency in north London.
