The 1980s
In 1984, the party chose Sharon Carstairs as its new leader. She was elected to the assembly in the 1986 election, and in the 1988 election, led the party to 20 seats and official opposition status. This was precipitated by the unpopularity of Howard Pawley's New Democratic government, which allowed the Liberals to win the support of many centre-left voters (the Liberals had largely abandoned their right-wing origins in the mid-1970s, particularly after Asper stepped down as party leader.)
This proved to be a temporary recovery. The NDP revived under Gary Doer, and the Liberals slipped back into third place in the 1990 election with only seven seats, against 20 for the NDP and 30 for the Conservatives.
