The second convicted terrorist, Rangzieb Ahmed, is the highest ranking member of al-Qaeda yet to be put on trial in Britain. Ahmed, 37, was at the centre of al-Qaeda’s global web and had links with every British terrorist cell including the July 7 and July 21 plotters. The first person to be convicted of “directing terrorism”, he alleges MI5 allowed him to leave Britain for Pakistan and tipped off intelligence services there so that he could be arrested in 2006 and tortured. Ahmed claims Britain was complicit in his torture.
