CHP votes fell even below the 1965 vote rates in 1969 elections. The two most important reasons of CHP’s decline were the centre-left politics’ causing loss of votes in the East and Southeast; and Unity Party of Turkey (Türkiye Birlik Partisi-TBP) being included into the party system with an aim to represent the Alevi. The TBP also pointed to a new functional division based on belief-identity in the party system.
