The participation of the Rassemblement Wallon (Walloon Gathering) in the Belgian government, from June 1974 to March 1977, pointed to great incoherence. Bebind the many incidents characterizing this experience, a ma;or change seems to have taken place within this party as well as in Belgian politics. Isolated in the government coalition, the RW was sub;ect to growing internal tensions, which resulted in the outline of contradictory strategies. The failure of its openings towards the right caused a rift in the party, thus necessitating alternate alliances with «the left», through a rapprochement towards the PSB (Belgian Socialist Party) and the FDF (Front of the French-speaking). This evolution highly contributed to the signing of an agreement between the three regions and to the onset of Belgium towards federalism.
