In 1973 the country became a one-party state; general elections in the same year saw Kaunda run unopposed for the presidency, with voters voting yes or no to his candidacy (89% voted in favour). The National Assembly now had 125 elected seats, ten presidential appointees and a Speaker elected from outside the chamber. Although UNIP was the only legal party, up to three UNIP candidates could contest each seat. The same system was used for elections in 1978, 1983 and 1988, with Kaunda re-elected each time.
