In 1961, Omer Vanaudenhove, leader of the Liberal Party, reorganised it into the Partij voor Vrijheid en Vooruitgang/Parti de la Liberté et du Progrès (PVV/PLP).

The PRL ministers in the government were: André Damseaux, François-Xavier de Donnea, Jean Gol, Louis Olivier, Charles Poswick, and Michel Toussaint.
In March 2002, the PRL merged with the German-speaking Party for Freedom and Progress (PFF) of the East Cantons, the Democratic Front of Francophones (FDF) and the Citizens' Movement for Change (MCC) into the Reformist Movement (MR).
