But in the debate on cohabitation that agitated the right between 1984 and March 1986 he sided with Raymond Barre, believing that a general election was - with the 1969 referendum that ended the political career of Général de Gaulle - valued as a test for or against the legitimacy of the President of the Republic.
From 1998 to 2004, he held the office of Médiateur de la République (Ombudsman), under which he chaired the Stasi commission to report on secularism in France.
This double hostility contributed to his parliamentary defeat in September 1986, during his candidacy for President of the Foreign Affairs Committee of the National Assembly against Roland Dumas, for the fall session of the year 1986.
Subsequent sessions of the spring and fall of 1987, Valéry Giscard d'Estaing maintained cohesion within the majority for the candidacy, while he solicited, by open letter, the votes of the National Front.
