Independent Radicals
In 1924, Radical-Socialists formed electoral alliances with the SFIO. The "Cartel des Gauches" (Coalition of the Left) won the 1924 legislative election and Herriot formed a government. However, the Radical-Socialists gradually drifted to the right, moving from left-Republican governments supported by the non-participating Socialists to a coalition of "Republican concentration" with the centre-right Independent Radicals and the more socially-conservative liberal parties in 1926.
