Now ex-Watford parliamentary candidate calls on Jeremy Corbyn to go

They have signed an open letter which indicates Labour would currently 'fail' in a general election and needs a leader who would be seen as a 'credible Prime Minister'.

Mr Turmaine, who lost out in the last general election battle in Watford, said the main job of the leader is to become PM and to 'keep the Tories out of number 10'.

He added: "When the results of the EU Referendum became clear, British politics changed irrevocably. Part of that change are the leadership crises impacting the Tory and Labour parties at present.

"Jeremy was elected by the party membership with a landslide, beating all opposition to claim the leadership on the first round.

"Jeremy has brought increases in membership, in Watford we saw a doubling of members, an incredible achievement.

"His idea of the new politics, with respect at its core has helped start to address the negative impression politicians have created amongst the public.

"But, Jeremy has lost the support of the overwhelming majority of MPs and MEPs and it therefore seems impossible that he can lead a united Labour Party to victory at such an election. This is a view shared by many of the people who voted for Labour in 2015. That is the reason that I have added my voice to those saying, we need to re-think. Labour has a better chance to do this with a different leader."

Watford’s Labour group last year decided to back Yvette Cooper rather than Jeremy Corbyn.

Mr Corbyn is still clinging onto his job despite losing two thirds of his entire shadow cabinet, with more than 40 MPs resigning over his leadership since Sunday.

The Labour leader lost a confidence vote among MPs on Tuesday night, has been told to go by all of his recent predecessors and was told by David Cameron to quit yesterday in the 'national interest'.

Watford's Consertive MP Richard Harrington makes light of the situation.

But amid the party's unprecedented state of crisis the letter is a fresh blow to his position.

It states: "We admire the service Jeremy Corbyn has offered to our party as leader in the past year, and his long service as an MP and within the union movement.

"However we believe we must accept that we cannot achieve our shared ambitions for the future of the United Kingdom, without a leader able to command the confidence of the country.

"That is why we believe Labour must seek a change of leadership,"

There is widespread Labour unease that if a snap election is called once the current shambolic state of Westminster is addressed, contesting it with Mr Corbyn in charge could prove fatal for the opposition party.

The entire fallout was triggered by dismal backing for Remain among Labour's voting heartlands in the EU referendum - followed by claims Mr Corbyn deliberately watered down his party's opposition to Brexit.

Watford Labour councillor Nigel Bell also said he wanted the embattled Labour leader to resign.

Councillor Stephen Cox, leader of Three Rivers Labour group described Mr Corbyn’s leadership as a “disaster all round” and said he had to go.    

Mr Corbyn sacked his shadow foreign secretary Hilary Benn in the early hours of Sunday, triggering waves of frontbench resignations.
