In 2006, the government refused to hold a public inquiry, stating that "it would be a ludicrous diversion". Prime Minister Tony Blair said an independent inquiry would "undermine support" for MI5, while the leader of the opposition, David Cameron, said only a full inquiry would "get to the truth". In reaction to revelations about the extent of security service investigations into the bombers prior to the attack, the Shadow Home Secretary, David Davis, said: "It is becoming more and more clear that the story presented to the public and Parliament is at odds with the facts."
