Botswana is a parliamentary republic in which the President of Botswana is both head of state and head of government. The nation's politics are based heavily on British parliamentary politics and on traditional Batswana chiefdom. The legislature is made up of the unicameral National Assembly and the advisory body of tribal chiefs, the Ntlo ya Dikgosi. The National Assembly chooses the president, but once in office the president has significant authority over the legislature with only limited separation of powers. The Botswana Democratic Party (BDP) rules as a dominant party; while elections are considered free and fair by observers, the BDP has controlled the National Assembly since independence. Political opposition often exists between factions in the BDP rather than through separate parties, though several opposition parties exist and regularly hold a small number of seats in the National Assembly.

The president of the Republic of Botswana is the head of state and the head of government of Botswana, as well as the commander-in-chief of the armed forces, according to the Constitution of Botswana.
