from times online: The full extent of what was known about the July 7 bombers was not disclosed to the parliamentary committee that investigated intelligence failings in the run-up to the suicide attacks.
MI5 is alleged to have kept back material from bugging operations and data gleaned from computer analysis of the bomb cell from the Intelligence and Security Committee before its critical report last week.
from the australian: British domestic spy agency MI5 is being accused of a cover-up for failing to disclose to a parliamentary watchdog that it bugged the leader of the July 7 London suicide bombers discussing the building of a bomb months before the attacks.
MI5 had secret tape recordings of Mohammad Sidique Khan, the gang leader, talking about how to build the device and then leave the country because there would be a lot of police activity.
But, despite the recordings, MI5 allowed him to slip the net. Transcripts of the tapes were never shown to the parliamentary intelligence and security committee, which investigated the attacks.
