Zanzibar has had Executive and Legislative Councils since 1 926 but it is since 1 957, when
elections were first held, that constitutional progress has been rapid. Under the 1961 constitu-
tion the country achieved an elected majority in the legislature and a ministerial system.
The political parties in Zanzibar are the Zanzibar Nationalist Party (Z.N. P.), the Zanzibar and
Pemba People’s Party (Z.P.P.P.) and the Afro-Shirazi Party (A.S.P.). The elections held in
January 1961 ended in deadlock so fresh elections were held in June. Following this, a
coalition of the Z.N. P. and Z.P.P.P. took office.
A constitutional conference was held in London in March 1962. A constitution for self-
government along the lines agreed at this conference, and including provision for a Bill of
Rights, was introduced in June 1 963 when the islands of Zanzibar and Pemba became internally
self-governing, prior to obtaining full sovereignty.
