Sao Tome and Principe country profile

Sao Tome and Principe, once a leading cocoa producer, consists of two islands of volcanic origin and a number of smaller islets lying off the coast of Africa.

From the late 1400s Portugal began settling convicts on Sao Tome and establishing sugar plantations with the help of slaves from the mainland. The island was also important in the transshipment of slaves.

The colony's aspirations for independence were recognised after the 1974 coup in Portugal and at first the Movement for the Liberation of Sao Tome and Principe was the country's sole political party. However, the 1990 constitution created a multi-party democracy.

The island of Principe assumed autonomy in 1995.

The country hopes to reduce its dependence on donors and cocoa exports by exploiting offshore oil. It has strong links with Angola, which is a major business partner.

President: Carlos Vila Nova

Sao Tome has a tradition of premiers and presidents from opposing camps governing together peacefully.

The president has an arbitrating role in government but no executive powers, leaving the prime minister in the dominant position.

Prime minister: Patrice Emery Trovoada

Patrice Emery Trovoada has been prime minister since November 2022. He previously served as prime minster during 2008, from 2010-2012 and again from 2014-2018. He is the son of former long-time President Miguel Trovoada.

He has said he wants to "reach the goal" of 40% women in his adminstration.

Freedom of expression, guaranteed by the constitution, is also respected in practice.

The state runs the only radio and TV stations but no law forbids private broadcasting.
