MI5 Files Must be Kept From 7/7 Victims' Families, Coroner Told http://www.guardian.co.uk/uk/2010/apr/28/mi5-files-7-7-victims-families-coroner

'Disclosing MI5 files about the July 7 suicide bombers to the families of those killed in the London attacks would be "impossible", counsel for the Security Service and the home secretary said today. Investigating claims that MI5 could have prevented the 2005 atrocities would involve "handing over the keys" to MI5's Thames House headquarters, Neil Garnham QC told a hearing to decide the scope of the inquests into the bombings.He said sensitive intelligence could be seen by the coroner and counsel to the inquests. However, any jurors would be subjected to intrusive vetting, he said, and neither the bereaved families nor their lawyers would be allowed to see it.'
