Though all nominations for the Central Committee are decided beforehand, since the 13th Party Congress in 1987, in the spirit of promoting "inner-party democracy", the number of candidates up for election for both full members and alternate members have been greater than the number of available seats. Nominees for the Central Committee who receive the lowest number of votes from Party Congress delegates are thus unable to enter the Central Committee. At the 18th Party Congress, a total of 224 candidates stood for election for full membership for a total of 205 seats. A total of 190 candidates stood for election for a total of 171 alternate seats. This meant that 9.3% of full member candidates and 11.1% alternate member candidates were not elected. The current Central Committee has 204 members and 171 alternates and was instated at the 19th National Party Congress.
