Spy's are real

Sophistication behind spy's poisoning

The poisoning of the former Russian spy Alexander Litvinenko would have required considerable scientific know-how, according to experts.

Mr Litvinenko's death on 23 November was linked to a "major dose" of radioactive polonium-210 found in his body.

Traces of radiation have since been found at five locations around London, including a sushi restaurant and hotel visited by the Russian.

But the radioactive substance implicated is as difficult to obtain as it can be to detect.

Polonium-210 occurs naturally in the environment and in people at low concentrations. But acquiring enough of it to kill would require individuals with expertise and connections.

Experts estimate that less than a microgram (one millionth of a gram) of the radioactive substance could have been responsible for Mr Litvinenko's death.

And another one:

Murdered British spy 'may have been killed by jealous lover'

Gareth Williams, 31, had been working for MI6 on a one-year posting but was due to return to his regular job at the GCHQ listening station in Cheltenham at the start of next month.

Detectives believe Mr Williams, whose body lay undiscovered for up to two weeks in the bathroom of his top floor flat, might have had a violent row with a lover over his decision to return to Gloucestershire.

However, police have not ruled out the possibility that the murder could be linked to his secret intelligence work.

Nick Clegg, the Deputy Prime Minister, was given updates on the investigation as part of a scheduled intelligence briefing yesterday.

Officers were yesterday examining Mr Williams’s mobile phone, which was found with several sim cards neatly laid out beside it, to find out his last contacts and when they were made. They were also studying CCTV images from cameras near the Georgian townhouse where Mr Williams had lived alone for the past year.
