"One of al-Qaeda's most dangerous figures has been revealed as a double agent working for MI5...

"Indignant French officials accused MI5 of helping the cleric to abscond. While he remained on the run, one intelligence chief in Paris was quoted as saying: “British intelligence is saying they have no idea where he is, but we know where he is and, if we know, I’m quite sure they do.”

On 12 November 2012, Abu Qatada won his appeal against deportation to Jordan to face trial and will be released.
