The Parliamentary Elections of 17 April 1977 revealed a great stability of the body of electors and largely confirmed the result of the communal elections of 1976. On the 393 seats in Parliament (House of Representatives and Senate), only 38 went to another political family.Nevertheless, this stability does not exclude movements; in this context should be noted the severe set-back of the «Rassemblement Wallon» which looses nearly half of its voters. Its defeat principally benefits the Liberals and the Christian Democrats and, to a lesser extent, the Socialists. In the Flemish region, the Socialists strengthen their position, whereas the Christian Democrats gain ground. Unexpected is the Liberals's setback. The «Volksunie» slightly recedes. In Brussels, PDF is undeniably successful and even exceeds its 1971 result. Communists are losing ground all over the country. In these elections which have been characterized by rather limited vote variations, the «communal tickets» (i.e. those based upon a single cultural group) recede, on the whole, to the benefit of the traditional parties which received a serious blow in 1971, but showed signs of a recovery as soon as 1974.
