BREAKING NEWS KGB double agent Oleg Gordievsky dies aged 86: Former British mole who leaked Russian secrets passes away in Surrey home after defecting in the 1970s

KGB double agent Oleg Gordievsky has died aged 86.

Gordievsky was said to be Britains most valuable spy inside Russias intelligence agencies.

A colonel in Russias KGB, Gordievsky, spent many years working as a double agent, passing vital intelligence to both Britains MI6 and MI5.

Counter-terrorism police are assisting the coroner, but his death is not being treated as suspicious.

He passed away peacefully at his home in Surrey, the BBC reports.

Gordievsky has lived in the ceremonial county under police protection since Moscow became suspicious of him in 1985 and he narrowly avoided arrest, trial and a firing squad by getting smuggled across the border into Finland in the boot of a car.

When the plum job of a posting to the KGB station in London came up in 1981, Oleg Gordievsky eagerly put himself forward.

He had been languishing in a desk job at headquarters in Moscow for three years. Here was a chance to get back into the game.

Gordievsky worked undercover for the KGB – the Soviet secret service – in London in the early Eighties, sending reports back to Moscow. 

But he was also, bravely, spying for the West. 

The London rezidentura was one of the most active in the world, and he would be handling secrets of the first importance.

He put on a show of enthusiasm, obsequiousness and fake humility to the boss whose decision it was — a thoroughly unpleasant character known as The Crocodile. Gordievsky loathed him.

But his toadying worked. He was appointed to the Soviet embassy in London, ostensibly to the diplomatic position of Counsellor but in reality deputy head of the KGB station housed there.

One by one, Gordievsky exorcised the demons of MI6 history.

For years there had been rumours of a ‘Fifth Man’, an unexposed member of the notorious Cambridge spy ring of Burgess, Maclean, Philby and Blunt. Gordievsky confirmed it was John Cairncross, a former MI6 officer.

He was able to name a Soviet spy discovered in 1946 but never formally identified, as Leo Long, a former intelligence officer, and that an Italian nuclear physicist, Bruno Pontecorvo, who worked on Britain’s wartime atomic bomb research, had volunteered his services to the KGB seven years before he defected to the USSR in 1950.

He also laid to rest the long-held conspiracy theory — on which much angst had been expended in the intelligence services — that Roger Hollis, a former chief of MI5, was a Soviet mole.

Most importantly, Gordievsky also put to rest MI6’s anxiety about current operations. MI6 had expected to learn that there was a vast network of KGB agents in Britain, communist spies like the Cambridge Five who had wormed their way into the Establishment to destroy it from within.

But Gordievsky told them that the KGB had only a small handful of agents, contacts and illegals in Britain, none very threatening.

Moreover, his insider’s depiction of KGB operations indicated that MI6’s Soviet adversary was not the invincible giant of myth, but flawed, clumsy and inefficient. It remained vast, well-funded and ruthless but its ranks included many time-servers, boot-lickers and lazy careerists with little imagination.

The KGB was still a dangerous antagonist, but its vulnerabilities and deficiencies were now exposed. It could be beaten.
