46,000 British troops, one-third of the total strength of the British Army (land forces), were deployed to assist with the invasion of Iraq. When after the war, no WMDs were found in Iraq, the two dossiers, together with Blair's other pre-war statements, became an issue of considerable controversy. Many Labour Party members, including a number who had supported the war, were among the critics. Successive independent inquiries (including those by the Foreign Affairs Select Committee of the House of Commons, the senior judge Lord Hutton, and the former senior civil servant Lord Butler of Brockwell) have found that Blair honestly stated what he believed to be true at the time, though Lord Butler's report did imply that the Government's presentation of the intelligence evidence had been subject to some degree of exaggeration. These findings have not prevented frequent accusations that Blair was deliberately deceitful, and, during the 2005 election campaign, Conservative leader Michael Howard made political capital out of the issue. The new threat of international terrorism ultimately led to the 7 July 2005 bomb attacks in London which killed 52 people as well as the four suicide bombers who led the attack.
