The country's worst-ever terrorist atrocity during London's morning rush hour on July 7, 2005, shattered for ever the heady euphoria in which the capital was basking the morning after winning the bid for the 2012 Olympics. That afternoon, Tony Blair - who was hosting the G8 summit on global poverty in Gleneagles, Scotland - returned to Downing Street to pronounce that the attack was an act in the 'name of Islam'. Later, at a meeting of the Government's national emergency committee COBRA, London's anti-terror police chief Andy Hayman told senior ministers that he suspected suicide bombers. And so the story of 7/7 that we have come to accept was pieced together: four British Muslims ... blew themselves up using home-made explosives, killing 56 and injuring 700 on three Tube trains and a double-decker bus. But families of the dead victims and an increasing number of 7/7 survivors claim there are inconsistencies and basic mistakes in the official accounts that need explanation. And they are demanding a full public inquiry to answer key questions about what the Intelligence Services and the police did and did not know before the bombings. Meanwhile, the Government's determined refusal to meet their demands is having a very dangerous side-effect - fuelling myriad conspiracy theories about 7/7. Books, blogs and several video documentaries point to oddities in the official accounts. [Some] of them suggest that the attacks were not the work of Muslim terrorists at all, but were carried out by the Government to boost support for the Iraq war. The survivors are so intent on an independent inquiry that they are now taking legal action in the High Court.
