Third Blair ministry

The third Blair ministry lasted from May 2005 to June 2007. The election on 5 May 2005 saw Labour win a historic third successive term in power, though their majority now stood at 66 seats – compared to 167 four years earlier – and they failed to gain any new seats. Blair had already declared that the new term in parliament would be his last.

The War in Afghanistan and the Iraq War continued during his last ministry, and the 7/7 bombings also took place. Blair's government responded by introducing a range of anti-terror legislation including the passing of the contentious Identity Cards Act 2006 legislation (repealed). Blair announced in 2006 that he would resign as prime minister and Labour leader within a year. He resigned on 27 June 2007 and was succeeded by Gordon Brown, who had been his chancellor of the Exchequer since 1997.
