A Staffordshire man who was famously pictured leading a woman to safety after the blast at Edgware Road Tube station said only a public inquiry would ensure all the lessons from July 7 were learnt.
Paul Dadge, from Cannock, said: "I will do whatever I can to campaign for a public inquiry."
The former fireman said the publicity heaped on him due to the photograph made him feel obliged to put pressure on the Government to do more to ensure an attack never happened again.
"I would hope that now we have a new Home Secretary, he will consider an inquiry. But I personally feel that one will only happen if the Government thinks it won't be held a ccountable for what happened."
One of the survivors of the attacks said the bomb-ers were so determined to kill themselves that nothing could have been done to prevent them.
George Psaradakis, who was behind the wheel of the No 30 double decker when it exploded in Tavistock Square killing 13 passengers, said: "My humble opinion is if a person is prepared to kill themselves and harm others, I don't think anyone can do something to prevent it."
There were mixed reactions from survivors to the findings of the Intelligence and Security Committee's report.
Some criticised the lack of resources which the document highlighted, while others said the security forces did what they c ould to prevent the attacks.
Michael Henning, a broker, from Kensington, west London, said: "I think the Government needs to be honest, I think we need an independent, probably public, inquiry."
Asked for his reaction to the suggestion that some of the bombers were not kept under surveillance b ecause of a lack of resources he replied.
"I think the lack of resources case is a scan-dal... At the end of the day I accept that the anti-terrorist police and MI5 are the experts.
"But at the end of the day you've got the police force who are quite capable of mounting surveillance, monitoring these people."
Grahame Russell, aged 63, whose son Philip, aged 28, from London, died in the bus blast, said security services had "no chance" of stopping it when faced with a lack of resources, although in his "heart of hearts" he did not think it could have been stopped anyway.
Asked about the report's conclusions about the security services he said: "I think they were under-resourced. I think they are also under-funded.
"I hear stories that there are 20 agents following a thousand suspects." But Mr Russell said there was nothing that could be done now.
Daniel Biddle, aged 27, who lost his legs and an eye in the Edgware Road blast, said the release of the reports would not help him come to terms with the events.
Mr Biddle, a building projects manager from east London who is still being treated in hospital, said: "To do a report a year on, it doesn't help anybody. To turn round and say no one was at fault, it doesn't help the survivor to get past it."
