A former Czechoslovakian spy has claimed that Jeremy Corbyn was paid by Communist secret police to inform on Britain.

Ján Sarkocy said he was posted to Britain as a diplomat under a false identity in the 1980s when he hired the MP as an “asset” codenamed COB.

According to the former spy, Soviet-backed Czechoslovakia’s Communist secret service Statni Bezpecnost (StB) regularly received information from the Labour figure, who documents show met with Mr Sarkocy on several occasions between 1986 and 1987.

Secret files seen by The Sun allege that Mr Corbyn was put on a list of StB sources in 1986, and that he handed over material relating to a government crackdown on Soviet spies.

The documents also noted the socialist MP was “negative towards USA, as well as the current politics of the Conservative Government”, and had a “positive” attitude towards Eastern Bloc countries.

After it emerged the Labour leader had met with Mr Sarkocy three times — including twice hosting him at the House of Commons — Mr Corbyn denied having had any knowledge that the Communist agent, who was operating in Britain under the name Lieutenant Jan Dymic, was a spy.

But, speaking for the first time about the claims, Mr Sarkocy insisted the Islington North MP was aware of his role in assisting the StB, telling reporters: “Everybody knew that ‘diplomat’ was just a cover for spy.”

“It was a consensual collaboration,” the former spy told Czech media, speaking while at home in his native Slovakia. “He was our asset, he had been recruited. He was getting money from us.”

While Mr Corbyn claimed in a statement issued this week simply to have met a Czech diplomat “for a cup of tea in the House of Commons”, the Slovak national alleged that after first meeting in “intellectual circles” the two had met on many more occasions than is documented in official records.

“It’s not important what you can find in official documents. Don’t forget, a lot of them were destroyed,” he said.

We don’t yet know the full details of the Corbyn/Communist spy thing, but the question that keeps bugging me is this: Why has Corbyn been approached by so many groups or regimes that wish to do Britain and her people harm? — James Cleverly (@JamesCleverly) February 17, 2018

Responding to the claims, a spokesman for the Labour leader said: “Jeremy was neither an agent, asset, informer nor collaborator with Czechoslovak intelligence. These claims are a ridiculous smear and entirely false.”

“The former Czechoslovak agent Jan Sarkocy’s account of his meeting with Jeremy was false 30 years ago, is false now and has no credibility whatsoever. His story has more plot holes in it than a bad James Bond movie.”

Officials from the Labour party pointed to the response to the allegations from Svetlana Ptáčníková, who heads the Czech Security Forces Archive responsible for safeguarding documents relating to the StB.

The archive director stated that Corbyn would not have known that Sarkocy was a spy, and that the MP was not a collaborator, according to the documents, or else his records would have been filed in a different category.

Breitbart London has previously reported how an unnamed former Special Branch officer disclosed that Mr Corbyn was monitored for twenty years by undercover security officers in the United Kingdom, who deemed the MP a “subversive” and feared he was engaged in activities intended to“undermine or overthrow parliamentary democracy” — likely as a result of his sympathy for groups like the terrorist Provisional Irish Republican Army (IRA).
