On Monday the BBC Panorama programme substantiated an extraordinary allegation that suggested how far the war on terror has descended into legal abyss. The claim was that MI6 rolled the pitch for Tony Blair's bizarre 2004 hug-in with Libya's Colonel Gaddafi by apparently arranging for the CIA to kidnap Gaddafi's opponent in exile, Abdel Hakim Belhaj. He was seized in Bangkok, where he and his wife were en route to Britain. It's been suggested they were "rendered" via the British colony of Diego Garcia to Tajoura jail in Tripoli. Belhaj spent six years, and his wife four and a half months, at the tender mercies of Gaddafi's security boss, Moussa Koussa.
