The Constitutional structure of the State is by and large similar to that of the Union. The executive power of each State is vested in the Governor of the State. The Governor of each State is appointed by the President on the advice of the Union Council of Ministers. The Governor is appointed for a term of five years but holds office during the pleasure of the President and can be removed any time.
The Governor acts on the advice of the State Council of ministers headed by the State Chief Minister. The Chief Minister is normally the leader of the political party commanding a majority in the Lower House or the only House of the State Legislature.
