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 new party, among other things, jettisoned the Liberals' traditional anti-clericalism. In 1965, the party obtained a victory in the general elections with 21.6% of the votes. In 1966, the PVV joined the government of Paul Vanden Boeynants. The liberal ministers during this period were Willy De Clercq, Jacques Van Offelen, Frans Grootjans, Herman Vanderpoorten, Charles Poswick and August De Winter.
On 27 June 1971, the party was split up in a Flemish (PVV) and Walloon party (the Liberal Reformist Party, PRL). Only a few months later, on 24 September 1971, the parliament was dissolved. In the elections which followed The Flemish PVV gained votes, but the Walloon PRL lost in the elections.
In this period (1971–1992), the PVV ministers in the government were: Willy De Clercq, Herman Vanderpoorten, Herman De Croo, Karel Poma, Alfred Vreven, André Kempinaire, Guy Verhofstadt, Louis Waltniel, Jean Pede, Patrick Dewael, Ward Beysen, and Jacky Buchmann.
The PRL ministers in the government were: André Damseaux, François-Xavier de Donnea, Jean Gol, Louis Olivier, Charles Poswick, and Michel Toussaint.
In Flanders, the PVV ceased to exist in 1992. On 15 November 1992, the Flemish Liberals and Democrats (VLD) was founded.
In 1976, the name of the party was changed into Parti des Réformes et des Libertés de Wallonie|Parti de Réformes et de la Liberté en Wallonie (PRLW). In 1979, the name was changed to Liberal Reformist Party (PRL) after the merger with the Liberal Party of Brussels. 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).
