The 29th Alberta Legislative Assembly was constituted after the general election on May 5, 2015. The New Democrats, led by Rachel Notley, won a majority of seats and formed the government. The Wildrose Party, which won the second most seats, formed the official opposition until July 2017, when it merged with the Progressive Conservatives, to become the United Conservative Party, which then became the official opposition.
