The truth about torture, terrorism and secrecy – as told by Britain's former spy chief

A year ago, the former head of MI5, Eliza Manningham-Buller, raised eyebrows in the darker recesses of Whitehall by telling some home truths in her BBC Reith lectures about the security and intelligence agencies.

She returns to her three key themes – torture, terrorism and secrecy – on Thursday with the publication of a short book, Securing Freedom, based on those lectures. It is a refreshing antidote to the rhetoric deployed by ministers and their acolytes who appear too frightened to come clean on any issue relating to that elusive but overarching concept of "national security". Here are some points that MI5, MI6, the CIA and the new justice secretary Chris Grayling should note:

1. "Torture is illegal in our national law and in international law. It is wrong and never justified ... Torture should be utterly rejected even when it may offer the prospect of saving lives … I am confident that I know the answer to the question of whether torture has made the world a safer place. It hasn't."

MI5 and MI6 remain embroiled in the unresolved dispute about their role in the abuse and torture of terror suspects. The government tried to push allegations under the carpet by compensating UK residents and citizens taken by the CIA to Guantánamo Bay – and no sooner had it done so than evidence emerged in Libya showing how MI6 helped arrange the abduction of Libyan dissidents to Tripoli, where they say they were tortured by Muammar Gaddafi's secret police. "There are clearly questions to be answered about ... whether the UK supped with a sufficiently long spoon," says Manningham-Buller, who was head of MI5 at the time. MI6, which was ultimately accountable to then foreign secretary, Jack Straw, says the rendering of the dissidents to Libya in 2004 was authorised by ministers.
