in August 1991. The constitution enlarged the National Assembly from 136 members to a maximum of 158 members, established an electoral commission, and allowed for more than one presidential candidate who no longer had to be a member of UNIP. The constitution was amended again in 1996 to set new limits on the presidency (including a retroactive two-term limit, and a requirement that both parents of a candidate be Zambian-born). The National Assembly comprises 150 directly elected members, up to ten (usually eight) presidentially appointed members, and a speaker. Zambia is divided into ten provinces, each administered by an appointed Provincial minister who essentially performs the duties of a governor. As of 2010, a new constitution is in the process of being drafted. Political history The major figure in Zambian politics from 1964 to 1991 was Kenneth Kaunda, who led the fight for independence and successfully bridged the rivalries among the country's various regions and ethnic groups.

Although not strongly supported in all areas of the country, only UNIP had a nationwide following. One-party state In February 1972, Zambia became a one-party state, and all other political parties were banned. Kenneth Kaunda sole candidate, was elected president in the 1973 elections. Elections also were held for the National Assembly. Only UNIP members were permitted to run, but these seats were sharply contested. President Kaunda's mandate was renewed in December 1978 and October 1983 in a "yes" or "no" vote on his candidacy. In the 1983 election, more than 60% of those registered participated and gave President Kaunda a 93% "yes" vote. 1991: Move to a multiparty state Growing opposition to UNIP's monopoly on power led to the rise in 1990 of the
