In 1989, after poor results in both the municipal elections and the European Parliament elections, Bayrou and twelve other centre-right parliamentarians including Philippe Séguin, Michel Noir, Alain Carignon, Étienne Pinte, Michel Barnier, François Fillon, Charles Millon, Dominique Baudis, François d'Aubert, Philippe de Villiers and Bernard Bosson demanded reform of the system at the RPR and the UDF, criticising the most prominent politicians of these parties including former president Valéry Giscard d'Estaing and Prime Minister Jacques Chirac. They called for the formation of a new right-wing party to unite the UDF and the RPR into a single entity. Ideological differences between members of this group led to members leaving, though d'Estaing endorsed Bayrou to become UDF general secretary in 1991.
