The decline of Social Credit and the unpopularity of the Liberals gave the New Democrats an opportunity to become the focus of opposition to the Lougheed-led Conservatives. Popularity of the NDP gradually increased under leader Grant Notley, who led the party from 1968 until his death in a plane crash in 1984, and was the party's sole MLA until 1982. In 1971, the NDP's popularity surpassed the 10% mark and went on to climb to 19% in the 1982 election. The party became the Official Opposition in 1982, though with only two seats. Notley was leading the NDP to what many thought was to be a major breakthrough before his death.
