The Labour government under Tony Blair was becoming unpopular because of the Iraq War. Michael Howard managed to reduce Labour's majority in parliament at the 2005 General Election, from 167 to 66. Howard resigned soon after this and David Cameron became Conservative Party leader. Camerom focused on modern and environmental issues. The Conservatives had a regular lead in opinion polls from 2007 onwards and at the 2010 General Election, the party won the most seats in parliament and the highest number of votes but was 20 seats short of a majority in parliament. A coalition government was made with the Liberal Democrats and David Cameron became Prime Minister in May 11, 2010. In the United Kingdom general election, 2015 the Conservatives won 331 seats. The first Conservative-majority government since 1992 was formed.
