The cabinet as a whole is responsible to the Lok Sabha . The Lok Sabha is a temporary house and can be dissolved only when the party in power loses the support of the majority of the house . The Rajya Sabha is a permanent house and can never be dissolved . The members of the Rajya Sabha are elected for a six - year term . </P> <P> The executive of government is the one that has sole authority and responsibility for the daily administration of the state bureaucracy . The division of power into separate branches of government is central to the republican idea of the separation of powers . </P> <P> The executive power is vested mainly in the President of India, as per Article 53 (1) of the constitution . The president has all constitutional powers and exercises them directly or through officers subordinate to him as per the aforesaid Article 53 (1). The president is to act in accordance with aid and advice tendered by the prime minister, who leads the council of ministers as described in Article 74 of the Constitution of India . </P> <P> The council of ministers remains in power during the' pleasure' of the president .
