MI5 has increased its surveillance of suspected Russian spies following the murder of Alexander Litvinenko in London
The director general of MI5, Jonathan Evans, told MPs on the Intelligence and Security Committee his agency was spending more time tracking Russian agents, with Russia accused of Cold War levels of espionage.
“In response to the Litvinenko murder, the Security Service increased its resource dedicated to Russia by around ***,” said the ISC's annual report for 2007-08, keeping exact details secret for security reasons.
Mr Litvinenko, a former agent for the FSB, the successor to the KGB, was poisoned by radioactive Polonium-210 in November 2006. The Kremlin has refused to extradite the main suspect, former KGB member Andrei Lugovoy.
