The Government of Barbados (GoB), is headed by the monarch, Queen Elizabeth II as Head of State. Since 1 June 2012, the Queen has been represented by the Governor-General, Sir Elliott Belgrave, G.C.M.G., K.A.
The country has a bicameral legislature and a political party system, based on universal adult suffrage and fair elections. The Senate has 21 members, appointed by the Governor-General on behalf of the monarch, 12 on the advice of the Prime Minister, two on the advice of the Leader of the Opposition, and seven in the Governor-General’s sole discretion. The House of Assembly has 30 members, all elected. Both houses debate all legislation. However, the House of Assembly may override Senate's rejection of money bills and other bills except bills amending the Constitution.
Officers of each house (President and Deputy President of the Senate; Speaker, Deputy Speaker, and Chairman of Committees of the Assembly) are elected from the members of the respective houses.
In keeping with the Westminster system of governance, Barbados has evolved into an independent parliamentary democracy and Constitutional monarchy, meaning that all political power rests with the Parliament under a non-political monarch as head of state, which allows stability. Executive authority is vested in the monarch, who normally acts only on the advice of the Prime Minister and Cabinet, who are collectively responsible to Parliament. Barbadian law is rooted in English common law, and the Constitution of Barbados implemented in 1966, is the supreme law of the land.
