British Columbia New Democratic Party
The party is the one governing the province right now. This is because there was a hung parliament after the 2017 elections and the BC Liberal Party did not win a motion of no confidence in the legislature. Instead, the BC NDP began a confidence and supply deal with the BC Green Party to form a minority government. Before that, the party governed British Columbia under six different premiers. They also won a majority government three times, in 1971, 1991, and 1996.
