The deputy chief minister is the Council of Ministers of Tamil Nadu's second-highest-ranking member. A deputy chief minister also holds a cabinet portfolio in the state ministry. In the legislative assembly system of government, the chief minister is treated as the "first among equals" in the cabinet; the position of deputy chief minister is used to govern the state with the support of a single party member, to bring political stability and strength within a coalition government, or in times of state emergency when a proper chain of command is necessary.
