Among the early acts of Blair's government were the establishment of the national minimum wage, the devolution of power to Scotland, Wales and Northern Ireland, major changes to the regulation of the banking system, and the re-creation of a citywide government body for London, the Greater London Authority, with its own elected-Mayor. Combined with a Conservative opposition that had yet to organise effectively under William Hague, and the continuing popularity of Blair, Labour went on to win the 2001 election with a similar majority, dubbed the "quiet landslide" by the media. In 2003 Labour introduced tax credits, government top-ups to the pay of low-wage workers. A perceived turning point was when Blair controversially allied himself with US President George W. Bush in supporting the Iraq War, which caused him to lose much of his political support. The UN Secretary-General, among many, considered the war illegal and a violation of the UN Charter. The Iraq War was deeply unpopular in most western countries, with Western governments divided in their support and under pressure from worldwide popular protests. The decisions that led up to the Iraq war and its subsequent conduct were the subject of Sir John Chilcot's Iraq Inquiry (commonly referred to as the "Chilcot report").
