集中と統一
During the course of the 1979–1982 legislature the party suffered a number of serious splits and defections. On 7 March 1980, Joaquim Molins resigned from the UCD group and later joined the Catalan Nationalist Convergence and Union. On 25 April 1980, Manuel Clavero resigned from the party in disputes over the statute of autonomy for Andalusia. Two months later, José García Pérez resigned over the same issue. García joined the Andalusian Socialist Party on 1 September 1981.
