SDLP

The Progressive Conservative Association of Alberta (often referred to colloquially as Progressive Conservative Party of Alberta) is a provincial centre-right party in the Canadian province of Alberta. The party formed the provincial government, without interruption, from 1971 until the party's defeat in the 2015 provincial election. With seven Premiers and at 44 years, this was the longest unbroken run in government at the provincial or federal level in Canadian history.
