A massive cache of stolen top-secret documents published in The Guardian has handed a ‘gift’ to terrorists, the head of MI5 warned last night.
In a blistering attack, Andrew Parker said the publication of confidential files leaked by US fugitive Edward Snowden had caused huge ‘harm’ to the capability of Britain’s intelligence services.
Security officials say the exposé amounts to a ‘guide book’, advising terrorists on the best way to avoid detection when plotting an atrocity.
