Radek Schovánek, an analyst with the defence ministry has spent 25 years researching documents filed by the now-defunct spy service. He told the Guardian the suspicions against Corbyn were unfounded, and the claims of Ján Sarkocy, a former intelligence officer expelled from Britain in 1989, to have signed the Labour leader up were false.
Schovánek said: “When you compare the documents which he had written and signed himself with what he is saying today, based on that he [Sarkocy] is a liar. He signed a list of documents in the UK which said Corbyn was an intelligence contact, not an agent.”
The term “intelligence contact” in reality meant little, Schovánek said. Czechoslovakian intelligence officers could have many such contacts, who provided little, if any information.
