A cohesive and consistent official opposition first formed when A. G. Blair formed the Liberal party in the early 1880s. Previously oppositions occasionally organized over major issues such as anti-prohibitionists led by John Hamilton Gray in the mid-1850s, and pro-Confederationists under Charles Fisher in 1865-1866.
^The Liberals won all seats in the Legislative Assembly in the 1987 Election. Camille Thériault was appointed by Premier Frank McKenna as Opposition Leader to ensure proper Parliamentary functions. During that time, no opposition leader, in the sense of the office being held by the leader of the largest non-governing political party, existed.
