The parliamentary committee tasked with monitoring the intelligence and security services has issued a call for evidence on Britain’s treatment of terror suspects during the so-called War on Terror.

The intelligence and security committee (ISC) launched an inquiry into the handling of detainees following the publication in December of the interim report of the aborted Gibson inquiry into allegations of British complicity in torture.

That inquiry, pledged by David Cameron in 2010, was scrapped in 2012 but its interim report suggested that British intelligence officers had been told they could turn a blind eye to breaches of the Geneva Conventions by CIA agents interrogating suspects in Afghanistan in 2002.
