Iain Duncan Smith served as Secretary of State for Work and Pensions from 2010 to 2016. A member and previous leader of the Conservative Party, Duncan Smith was appointed to the cabinet by Prime Minister David Cameron following the 2010 general election and the formation of the coalition government between the Conservatives and the Liberal Democrats. He was reappointed after the Conservatives won a majority in the 2015 general election but resigned in March 2016 in opposition to disability benefit cuts.
