A Russian spy who infiltrated Britain’s top secret GCHQ base is passing secrets to Moscow, a former major in the KGB says.
Defector Boris Karpichkov claims to have has new evidence backing his dramatic claim that body-in-a-bag victim Gareth Williams was murdered because he knew the Russian mole’s identity.
Maths genius and GCHQ codebreaker Williams, 31, was found dead, padlocked inside a holdall in the bath at his London home in August 2010.
At the time of his death he was on secondment to MI6.
Karpichkov, 56, who by coincidence lived near Williams’ flat in Pimlico, south London, has been investigating the mysterious death ever since.
