Mouvement Réformateur
The Parti Socialiste (PS) is a social-democratic party that took part in the Verhofstadt I Government and the Verhofstadt II Government. It is unlikely that the PS will deliver Belgium's next prime minister, the last Francophone prime minister was Paul Vanden Boeynants in 1978-79. Largest competitor of the PS is the Mouvement Réformateur (MR), which just recently broke with the PS in Charleroi, after PS aldermen were charged with corruption.
