King became Premier in 2019 when his party formed a minority government, which became a modest majority as a result of by-election wins. At the dissolution of the Legislature, the PCs had 15 seats, the Greens were the Official Opposition with eight seats, while the Liberals held four. The 2019 election marked the first time that the Green Party formed the Official Opposition in any jurisdiction in Canada.

Given the significant losses by the Greens tonight, the Liberal Party, despite suffering losses, will form the official opposition, holding three seats, compared to two for the Green Party.

Liberal Leader Sharon Cameron failed to secure a seat, coming third in her riding, where she campaigned against the winner, Green Leader Peter Bevan-Baker, and PC candidate Donna Docherty.

The Liberal Party will most likely name an interim leader, who will become opposition leader, in time for the return of the Legislative Assembly.

One notable win tonight was that of Rob Lantz, the former PC party leader, who was victorious in the riding of Charlottetown-Brighton.
