On 26 November 1951, during the ninth CHP Congress, the youth branch and the women's branch of the CHP were formed. On 22 June 1953, the establishment of trade unions and vocational chambers was proposed, and the right to strike for workers was added to the party program. On 2 May 1954, the CHP lost a second consecutive general election to the DP, gaining only 31 seats with 35.4% of the total vote. The DP captured 505 seats with 57.6% vote, due to the winner-take-all system in place. Following this defeat, the CHP began intensifying its opposition tactics and increased its share of the votes to 41%, gaining 178 seats, in the 27 October 1957 elections. The DP gained 424 seats with 47.9% vote amid growing concerns about the DP's authoritarian tendencies in government.
