Shortly after the legalisation, a group of SHP MPs resigned from the party and refounded the Republican People's Party (CHP), Erdal İnönü's father's party (most party members were pre-1980 CHP members). The SHP and the CHP, two similar parties, co-existed for a while. On 6 June 1993 İnönü announced that he was planning to resign and Murat Karayalçın was elected as the new president of the party on 11 September 1993.
