Jeremy Corbyn's closest allies believe his position on Brexit is "bonkers", according to former Labour spin doctor Alastair Campbell.
Mr Campbell, who served under Tony Blair and helped win the party three general elections, said Corbyn's muted support for another referendum was isolating him from his frontbench colleagues.
Speaking on BBC Radio 4's Today programme, Mr Campbell listed the names of those who disagreed with Corbyn, in what was his first interview since [being expelled from Labour after he admitted to voting Liberal Democrat at the recent European elections](http://Former spin doctor Alastair Campbell expelled by Labour Party over European election vote).
He said: "I have had it clearly spelled out to me by people from Keir Starmer to John McDonnell, I’ve heard it publicly from Shami Chakrabarti, from Tom Watson, Emily Thornberry.
“They all think this decision is bonkers and they all think it should be reviewed.
“It’s a question of whether the Labour Party wants to do the right thing on Brexit or whether it just wants to have these distractions where we can talk about process, talk about nonsense, and not face up to the decisions that real leaders would make on the single most important issue facing the country.”
Using Labour's "for the many not the few" slogan, made popular by Corbyn, he said the party leader needs to listen why it was "virtually annihilated" at last week's election.
Campbell blamed Corbyn's "very, very small clique" of advisers for refusing to embrace a second referendum.
He said: “Jeremy Corbyn needs to decide if he is going to listen to the many – the public, the members, the MPs – or the few – Seumas Milne, Karie Murphy, Len McCluskey and Andrew Murray.
“They are the people driving this and they are the people risking oblivion for the Labour Party.”
Mr Campbell added there was "no justification" for his explusion from Labour.
He added: “The reason there is no justification for this expulsion is because, as Shami Chakrabarti said yesterday, a tactical vote is not a reason for expulsion,” he said.
“The only evidence provided to me were three cuttings covering what I’d said after the event, after the polls had closed, after the results had come in.”
Defending his comments on the eve of poll that he understood people who were not planning to vote Labour, he said: “That’s hardly campaigning for another party.”
