An extraordinary example occurred in Alberta, Canada, in December 2014 by Danielle Smith, the Leader of the Official Opposition. She and eight of her MLAs, all of the Wildrose Party, crossed the floor together to join the governing Progressive Conservative Association of Alberta. In 2019, eleven British MPs defected from the Conservative and Labour parties to form the centrist Change UK party. In September 2019, the governing Conservative party lost its working majority when Phillip Lee MP defected to the Liberal Democrats during the first speech of new prime minister Boris Johnson.
