LABOUR’S civil war intensified yesterday after Tom Watson criticised the party’s leadership for revoking Alastair Campbell’s membership.

Tony Blair’s former spin doctor, who has become one of the most prominent campaigners for a second Brexit referendum, was booted out of the party after he told the BBC that he’d voted for the LibDems in the European elections.

Watson, who is Labour’s deputy leader, called the decision “spiteful” and demanded an “amnesty” for members who voted against the party.

Campbell’s ousting led to a number of Labour grandees admitting that they too had voted for a different party, daring the Labour to expel them as well.

Watson said: “It is very clear that many thousands of Labour Party members voted for other parties last week,” he said.

“They were disappointed with the position on Brexit that a small number of people on the NEC inserted into our manifesto. They were sending the NEC a message that our position lacked clarity and they were right.

“It is spiteful to resort to expulsions when the NEC should be listening to members.

He added: “The politics of intolerance holds no future for the Labour Party. A broad church party requires pluralism and tolerance to survive.

“There should be an amnesty for members who voted a different way last week.”

That came as former Labour Home Secretary Charles Clarke admitted that he too backed the LibDems.

Clarke blasted called for Campbell’s expulsion to be overturned. He said: “I also voted Liberal Democrat. This was a one-off decision because of the hopeless incoherence of Labour’s position, particularly that of Jeremy Corbyn, on Brexit.”

Meanwhile, former defence secretary Bob Ainsworth said he voted for the Greens during last week’s election. David Martin, the outgoing Scottish Labour MEP said he was “getting increasingly angry with senior Labour people boasting they voted Liberal Democrat.”

“Don’t know why they feel so proud to have eliminated hard working pro Europe MEPs or feel so smug about doing long term damage to @UKLabour,” tweeted.

John Prescott added: “Like millions of others, I voted Labour in the Euros. Just as I have in every election for the past sixty years. Never voted for another party. And I never will.”

Meanwhile, the shock resignation of Scottish Labour MSP Neil Findlay forced beleaguered party leader Richard Leonard was to step in to speak during yesterday’s Holyrood statement on the SNP’s new independence legislation.

Just 14 of his 23 MSPs turned up.

SNP Brexit secretary Michael Russell paid a tongue-in-cheek “brief tribute” to his “former shadow”.

“Although it is no secret that he and I were not soul mates, I regret that any individual has decided that they do want to continue in the role, and I absolutely wish him well in the future,” he said.

“I hope that, whatever he decides to do, he enjoys it more than being a member of the Labour group.”

However, reports suggested a planned coup against Leonard had been put on ice, with plotters refusing to quit their front bench jobs.

“They have had all week to come up with a plan but they didn’t have the balls,” a source on the moderate wing of the party told The Times.

“It feels like the death of the party,” they added.
