The Radical Party (Parti Radical, Rad., also known as Parti radical valoisien) is a liberal and centrist political party in France. Founded in 1901 as Republican, Radical and Radical-Socialist Party (Parti républicain, radical et radical-socialiste), it is the oldest active political party in France. Coming from the Radical Republican left-wing tradition, the Radical Party upholds principles of private property and secularism. The Radicals were considered in the 1880s as a far left group, but with the emergence of the Socialists in 1905, they shifted to the centre-left. Since then they have shifted increasingly to the centre and finally to the centre-right. They are currently an associate party of the conservative Union for a Popular Movement.
