MI5 is facing an internal revolt by officers alarmed about intelligence failures and the lack of resources to fight Islamic terrorism. To illustrate their concern, agents have leaked more topsecret documents to The Sunday Times because they want a public inquiry into the missed intelligence" leading up to the July attacks in London. They believe ministers have withheld information from the public about what the security services knew about the suspects before the bombing of July 7 and the abortive attacks of July 21. The documents include an admission by John Scarlett, head of SIS, the secret intelligence service (also known as MI6), that one of the July 21 suspects was tracked on a trip to Pakistan just months before the attempted bombings. MI5, which is responsible for national security, allowed the July 21 suspect to travel to Pakistan after he was detained and interviewed at a British airport. It stopped monitoring him because it said "the Pakistani authorities assessed that he was doing nothing of significance". They are critical of Blair, who has ruled out an inquiry saying it would distract the security services from fighting terrorism. The assessment echoes a decision by MI5 to halt surveillance on two of the July 7 bombers 16 months before the attacks. Both were filmed and taped by MI5 agents as they met two men allegedly plotting to carry out a terrorist attack in England.
