Jacqui Putnam, a survivor of the Edgware bomb in July 2005, said last night: "We were told that the 7/7 bombers were working alone and that they were just guys who got together and decided to do this without visiting any other agency and now we know that they were part of an organised network."
Joining relatives of those killed in issuing fresh calls for a public inquiry into the attacks she said yesterday's revelations called into the question parts of the reports into the bombings.
"Certainly the bits where they said that the 7/7 bombers were acting alone, obviously that's not true, it raises the question of what else is wrong."
John Falding, whose partner Anat Rosenberg died in the Tavistock Square bus bomb, said: "It may be that this is why the Government bizarrely resisted all the pressure for an independent public inquiry."
But despite the security service's inability to prevent the 7/7 bombings he said that MI5 should be praised for foiling the fertiliser plot.
Grahame Russell, who son Philip died in the Tavistock Square bombing said: "I believe that there is still a lot more to come out."
