Trinidad and Tobago: Government Structure

Trinidad and Tobago is a parliamentary democracy and unitary republic, with a system of government modeled on the Westminster tradition inherited from British colonial rule. The country adopted a republican constitution in 1976, replacing the British monarch as head of state with a president while retaining a parliamentary cabinet system. The president serves as the largely ceremonial head of state, elected for a five-year term by a majority vote of the combined houses of Parliament, while the prime minister holds executive authority as head of government.

Parliament is bicameral, made up of a House of Representatives and a Senate. The House has 41 members elected from single-seat constituencies for terms of up to five years, and following a general election the president appoints as prime minister the person best able to command the support of a majority in the House. The Senate has 31 appointed members: 16 chosen on the advice of the prime minister, six on the advice of the leader of the opposition, and nine independent senators appointed at the president's own discretion.

The cabinet, led by the prime minister and drawn largely from the elected House, directs government policy and is collectively answerable to Parliament. The judiciary operates independently under a Chief Justice, with the Trinidad and Tobago legal system rooted in English common law and final appeals historically heard by the UK-based Judicial Committee of the Privy Council, though the country has also worked toward greater use of the regional Caribbean Court of Justice. Local government is organized through regional corporations and municipalities, while Tobago holds a measure of self-governance through its own elected House of Assembly, which manages island-specific matters such as infrastructure, health, and education.
