West Bengal is governed through a parliamentary system of representative democracy, a feature the state shares with other Indian states. Universal suffrage is granted to residents. There are two branches of government. The legislature, the West Bengal Legislative Assembly, consists of elected members and special office bearers such as the Speaker and Deputy Speaker, that are elected by the members. Assembly meetings are presided over by the Speaker or the Deputy Speaker in the Speaker's absence. The judiciary is composed of the Calcutta High Court and a system of lower courts. Executive authority is vested in the Council of Ministers headed by the Chief Minister, although the titular head of government is the Governor. The Governor is the head of state appointed by the President of India. The leader of the party or coalition with a majority in the Legislative Assembly is appointed as the Chief Minister by the Governor, and the Council of Ministers are appointed by the Governor on the advice of the Chief Minister. The Council of Ministers reports to the Legislative Assembly. The Assembly is unicameral with 295 Members of the Legislative Assembly, or MLAs, including one nominated from the Anglo-Indian community. Terms of office run for 5 years, unless the Assembly is dissolved prior to the completion of the term. Auxiliary authorities known as panchayats, for which local body elections are regularly held, govern local affairs. The state contributes 42 seats to Lok Sabha and 16 seats to Rajya Sabha of the Indian Parliament.
The main players in the regional politics are the All India Trinamool Congress, the Indian National Congress, the Left Front alliance (led by the Communist Party of India (Marxist) or CPI(M)). Following the West Bengal State Assembly Election in 2011, the All India Trinamool Congress and Indian National Congress coalition under Mamata Banerjee of the All India Trinamool Congress was elected to power (getting 225 seats in the legislature) . West Bengal had been ruled by the Left Front for the past 34 years, making it the world's longest-running democratically elected communist government.
