The Deputy Prime minister of India is a member of the Union Cabinet in the Government of India. Not technically a constitutional office, it seldom carries any specific powers. A deputy prime minister usually also holds a key cabinet portfolio such as home minister or finance minister. In the parliamentary system of government, the prime minister is treated as the "first among equals" in the cabinet; the position of deputy prime minister is used to bring political stability and strength within a coalition government or in times of national emergency, when a proper chain of command is necessary.
