Dissidents to sue former head of UK counterterrorism over his alleged role in their rendition to Libya.

Two Libyans are suing the former counterterrorism chief of Britain’s foreign intelligence service over his alleged role in their illegal rendition.

Sami al-Saadi and Abdel Hakim Belhadj, the head of Tripoli’s Military Council, both say they were tortured under former Libyan leader Muammar Gaddafi, after the UK’s MI6 agency helped to abduct them abroad.

The cases are already being investigated by police, but now the men are suing Sir Mark Allen for “complicity in torture”.
