An MI5 agent was allegedly recruited by a terrorist mastermind in Syria and sent back to Britain in a plot to launch a devastating attack against his handlers. The agent was recruited by MI5 as an undercover informant within the radical Islamic community and he then travelled to Syria where he became part of a jihadist group.
But he apparently double-crossed his British handlers and returned to London with plans to launch an 'insider attack' in the capital.
The Mail on Sunday has been aware of the alleged plot for more than a year but agreed to previous requests from the security services not to publish the story for 'national security' reasons.
Parts of the plot were reported in a story in The Mail on Sunday last year, in which we revealed that the jihadist, who has a British passport, had plans to attack Central London and that David Cameron had been briefed about the details.
This newspaper is aware of the man's identity and further details of the investigation but are not printing them for legal reasons.(...more)
