Survey of trade unionists reveals unease over Jeremy Corbyn leadership

But as both factions in the party have used social media campaigns to encourage supporters to sign up, it is not clear whether the boost in membership would benefit Mr Corbyn, who was swept into the leader’s office on the back of a grassroots movement a year ago.

And yet he could still win another party leadership contest, according to the latest poll of members.

However, the Labour leader retains considerable support from grassroots members.

Lord Kinnock urged Mr Corbyn’s supporters to think about whether they wanted to “turn up at the funerals of communities and industries” caused by decades more of Conservative rule.

While Corbyn has never been popular among Labour members of Parliament, unseating him may not be easy.

The Labour leader, who has lost the confidence of more than three-quarters of his MPs, has repeatedly told those pleading with him privately to go that he can not let down the 250,000 party members and supporters who gave him a resounding victory in last year’s leadership election.

The surge puts Labour’s new total member base at 450,000 – higher than its last peak of 440,000 under former Prime Minister Tony Blair.

“I’d like him to go, and nominate someone else who isn’t Jeremy Corbyn”.

“He’s been asked to stand down and at the moment we want him to consider his position and do what is right in the interests of the party”, Eagle said.

But he said: “For a democracy to function, you’ve got to have an opposition with the minimum level of credibility to challenge the government and to hold it to account”.

While just 35 per cent said Mr Corbyn should stay at the helm in the face of overwhelming opposition from MPs, MEPs and politicians in Scotland.

“I think they need to reconsider what they’ve done”.

But she added that Mr Corbyn should be encouraged to do “the right thing for the party and the country”.

“Until such a contest is declared, Pendle CLP will not be making any further comment with regards to Jeremy Corbyn’s leadership”.

But Len McCluskey, one of Mr Corbyn’s most prominent supporters, said it was “outrageous” that grandees were “being dragged out to be part of this unedifying coup”.

“And here’s the truth”. The coup has failed.

Corbynite pressure group Momentum is expected to muster thousands of activists in a series of emergency rallies to counter what it describes as the “deeply undemocratic” efforts to oust Jeremy Corbyn.

A letter addressed to Labour headquarters on behalf of Labour councillors across the country claims he is “unable to command the confidence of the whole party”.
