They were the first elections after the Second World War and saw fundamental changes among the political parties. The Flemish National Union, which held 17 seats prior to the war and collaborated with Nazi Germany during the war, was outlawed. The Catholic Party changed into the Christian Social Party while the Belgian Labour Party changed into the Belgian Socialist Party. The Liberal Party suffered major losses, while the Christian Social Party and the Communist Party made major gains.

Following the elections, Paul-Henri Spaak formed a Socialist minority government supported by the Communists. After he failed to win the confidence of the Christian Social and Liberal parties, outgoing PM Achille Van Acker formed a new government which included Socialists, Communists and Liberals.
