Captured documents relevant to Belhadj's suit in the U.K. reportedly include a letter dated March 18, 2004 from Sir Mark Allen, formerly the head of counterterrorism at MI6, to Moussa Koussa, the head of Libyan intelligence stating:
I congratulate you on the safe arrival of Abu Abdullah al-Sadiq [Belhadj]. This was the least we could do for you and Libya to demonstrate the remarkable relationship we have built over the years. I am so glad. I was grateful to you for helping the officer we sent out last week.The Belhadj lawsuit joins another one against the U.K. government filed in October by Sami al-Saadi, which also relates to involvement by U.S. and U.K. authorities in his rendition and is also based, in part, on captured documents from Tripoli.
