His true feelings come despite the TV journalist-turned-author publicly championing Mr Corbyn at major rallies through out Labour’s leadership contest, including one outside Parliament.

The left wing former Newsnight and Channel 4 News economics correspondent also revealed he wants to replace Mr Corbyn with shadow business secretary Clive Lewis.

The conversation - at the troubled party’s conference in Liverpool two weeks ago - was recorded by a bystander and passed to The Sun.

In it, Mr Mason said: “Corbyn doesn’t appeal to the mainstream working class vote.

“It’s to do with a cultural thing about London.

“Corbyn goes to England on a bike and cycles round.

“Working class people go to a leader.

“He has no cultural references to the way they live”.

Mason’s plotting will come as a hammer blow to Mr Corbyn.

Over the summer during the leadership fight , Mr Mason said of the Opposition boss: “Jeremy Corbyn will win.

“He will be in a position to form a government.

"The most radical thing you can do is vote for Jeremy Corbyn.”

But he also loudly told the confidante over the lunch in a restaurant that former shadow defence secretary Clive Lewis would connect with voters far better, despite being “not a very convincing politician” yet.

Mr Mason told the friend: “The person who I would replace Corbyn with eventually is this guy called Clive Lewis.

Ex-Army reservist and Norwich South MP Mr Lewis, 45, was demoted by Mr Corbyn in his shadow cabinet reshuffle last week after clashing with his lifelong CND supporter boss over whether to keep Trident nuclear missiles.

“He’s good. He’s to the right of Corbyn.

“Not a very convincing politician, he’s not 30 years of ultra left, but he’s good.

“He’s good enough for me.

“Mainstream working class voters like big… to be honest if Clive stood, that’s what they want - somebody with a big ego who would shout.”

Mr Mason is loathed by moderate Labour MPs.

The 56-year-old activist has a huge social media following and is known for whipping up deselection witch hunts against them if they publicly challenge Mr Corbyn’s right to run Labour.

When confronted by The Sun last night, Paul Mason admitted having the conversation, and said it was with a visiting Spanish MP.

Issuing a diatribe of vile abuse at the newspaper for exposing his real views, Mr Mason also said: "I'm proud to have played a part in Jeremy Corbyn's re-election as leader".
