UK intelligence 'unaware' of waterboarding interrogation

George W Bush claims lives were saved by the use of information obtained from terrorist suspects by "waterboarding" but a former chair of the Commons Intelligence and Security Committee says UK intelligent services were not aware of it.

The interrogation technique - which simulates drowning - had helped to break up plots to attack Heathrow airport and Canary Wharf, according to the former US president.

Although the UK intelligence services do not condone the technique there are no guarantees on how information is obtained, said Dr Kim Howells.
