Politics in Grenada takes place in a framework of a parliamentary representative democracy, whereby the Prime Minister is the head of government. Grenada is an independent Commonwealth realm. It is governed under a multi-party parliamentary system whose political and legal traditions closely follow those of the United Kingdom; it has a prime minister and a cabinet, and a bicameral Parliament with an elected House of Representatives and an appointed Senate. Executive power is exercised by the government. Legislative power is vested in both the government and parliament. Constitutional safeguards include freedom of speech, press, worship, movement, and association. Grenada is a member of the eastern Caribbean court system. The Judiciary is independent of the executive and the legislature. Jurisprudence is based on English common law.

The Head of State

Grenada is a parliamentary democracy within the Commonwealth with Her Majesty Queen Elizabeth II as the nominal head of state represented in the country by the Governor-General.

The Prime Minister and Head of Government

The Prime Minister is appointed by the Governor-General as the Representative who appears likely to command the support of the majority of the Representatives in the House of Repreentatives.

The Cabinet

The Cabinet is appointed by the Governor-General on the advice of the Prime Minister from the members of the House of Repreentatives, with no more than two members being drawn from the appointed senators.  The main function of the Cabinet is to advice the Governor-General and is collectively responsible to the House for any advice given to the Governor-General by or under the general authority of the Cabinet and for all things done by or under the authority of any Minister in the execution of his office.

The legislature is bicameral, with a lower house, the House of Representatives, and an upper house, the Senate. The country has 15 constituencies and these 15 single-member seats in the House of Representatives are contested in General Elections: members are elected by popular vote on a first-past-the-post basis, to serve five-year terms. The leader of the party securing the majority of seats in Parliament is named Prime Minister by the Governor-General. The leader of the party winning the next largest bloc of seats is named leader of the Opposition.

The 13 members of the Senate are appointed politically. The Prime Minister recommends the appointment of seven senators of his or her own choosing, plus an additional three senators who are to be selected in consultation with the organizations or interests which the Prime Minister considers the Senators should be elected to represent. These organizations and interests traditionally encompass agricultural and business groups as well as trade unions. The leader of the Opposition is entitled to nominate three Senators.

The suffrage is from 18 years.

As in other English-speaking Caribbean countries, the judiciary in Grenada is rooted in British common law.  The judicary includes the Eastern Caribbean Supreme Court, consisting of a court of Appeal and a High Court of Justice (two High Court judges are assigned to and reside in Grenada); Itinerant Court of Appeal three judges; member of the Caribbean Court of Justice (CCJ)
