Libyan government papers pieced together by [a] team of London lawyers show [that] Tony Blair wrote to Colonel Muammar Gaddafi to thank him for the excellent cooperation" between the two countries' counter-terrorism agencies. The letter, written in 2007, followed a period in which the dictator's intelligence officers were permitted to operate in the UK, approaching and intimidating Libyan refugees. Addressed "Dear Mu'ammar" and signed "Best wishes yours ever, Tony", the letter was among hundreds of pages of documents recovered from Libyan government offices following the 2011 revolution. Six Libyan men, the widow of a seventh, and five British citizens of Libyan and Somali origin are bringing claims against the British government on the basis of the recovered documents, alleging false imprisonment, blackmail, misfeasance in public office and conspiracy to assault. The recovered documents show that MI5 and MI6 submitted more than 1,600 questions to be put to two opposition leaders after they had been kidnapped with British assistance and flown to one of Gaddafi's prisons. Both men say they suffered appalling torture. On Thursday an attempt by government lawyers to have the case struck out without admitting liability failed when the high court ruled the allegations "are of real potential public concern" and should be heard and dealt with by the courts.
