Complicit: one-off drama

Gordon Brown inspired this MI5 drama in 2009, when he said the British state did not engage in torture.

Producer Kevin Toolis began a long research project into the intelligence services and terrorism.

The result is Complicit, a hard hitting drama about a British agent (played by David Oyelowo) desperate to convict someone he believes is a terrorist.

He follows his suspect to Egypt, and tries to create the facts to prove his case.

Written by Guy Hibbert.
