A FORMER FBI agent and alleged torturer should have been arrested on arrival at Parliament yesterday, a human rights group has said.

Ali Soufan was hosted by the right-wing Henry Jackson Society on Thursday as a guest speaker at the House of Lords to promote his new book Anatomy of Terror.

But Mr Soufan’s invitation stirred controversy as the former FBI agent faces accusations of complicity in the torture of Qatari businessman Ali al-Marri on US soil.
