Jeremy Corbyn has rubbished suggestions that he provided information to a Communist spy during the Cold War.
Files obtained by The Sun allegedly suggest that Corbyn met a Soviet-backed agent from Communist Czechoslovakia, Lieutenant Jan Dymic, three times during the 1980s - including twice in the House of Commons.
The Sun's report further claims that Corbyn proferred information about the arrest of an East German, and was put on a list of agents and sources - even receiving the codename COB.
However a spokesperson for the Labour leader said: "The claim that Jeremy Corbyn was an agent, asset or informer for any intelligence agency is entirely false and a ridiculous smear.
"Like other MPs, Jeremy has met diplomats from many countries. In the 1980s he met a Czech diplomat, who did not go by the name of Jan Dymic, for a cup of tea in the House of Commons. Jeremy neither had nor offered any privileged information to this or any other diplomat.
"During the Cold War, intelligence officers notoriously claimed to their superiors to have recruited people they had merely met. The existence of these bogus claims does not make them in any way true, as The Sunday Times found out to its cost when it published fabricated allegations about former Labour leader Michael Foot and the KGB."
