According to the Indian Constitution, the elected head of the council of ministers in a state is the Chief Minister (CM). Although, the Governor is the official ‘head of the state’, yet it is the Chief Minister who is vested with the ‘de facto’ executive powers.
Chief Minister is the real head of a state, unlike the Governor, who is the ceremonial head. Since India has adopted the Westminster Model of constitutional democracy, it is the CM who oversees the day-to-day functioning of the state government.
According to the Indian Constitution, in the everyday administration, the CM is assisted by the council of ministers, which consists of cabinet ministers, deputy ministers and others. The CM is appointed by and sworn in by the Governor.
