Canada’s 16th prime minister and a member of the Progressive Conservative Party, Clark defeated the Liberal government of Pierre Trudeau in the 1979 election.

His brief tenure with a minority government made it challenging to pass legislation and his government was brought down following a non-confidence vote on his first budget, leading to the 1980 election and ultimately Trudeau’s return to power.

Clark later served in Mulroney’s cabinet as the Secretary of State for External Affairs from 1984 to 1991 and as the minister responsible for constitutional affairs.

Clark opposed the merger of the Progressive Conservatives with the Conservative Party of Canada and sat as an independent Progressive Conservative until his retirement from Parliament at the end of the 2003 session.

Since then, Clark has worked for a number of non-profits, including The Woodrow Wilson International Center for Scholars, the Centre for North American Studies, the Jimmy Carter Center, the Global Leadership Foundation and the Centre for International Governance Innovation.
