The National Assembly is the parliament of Saint Kitts and Nevis. The assembly has 14 or 15 members (depending upon circumstances), 11 of whom are elected for a five-year term in single-seat constituencies and are known as Representatives. The remaining four are called Senators; three are appointed by the governor-general and the fourth is the attorney-general (i.e. an ex officio member).
The 1983 constitution mandates at least three senators, or four if an attorney-general is not one of these three appointed senators. The number can be increased by the parliament as long as it doesn't exceed two thirds of the number of representatives. Except for the attorney-general, the senators are appointed by the governor-general, acting on the advice of the prime minister in two of the appointments and the leader of the opposition for the third one.
