French social reform party.
Founded in 1944, the MRP was a strong centre party of the Fourth Republic and the French expression of Christian Democracy . After winning about 25% of the vote, it declined in the 1950s, losing strength to both right and left factions. In 1966 it was merged with other right-centre parties to become the Centre Démocrate, which won only 13% of the vote. By 1968 it had become little more than a political club.
