A deputy chief minister also holds a cabinet portfolio in the capital territory 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 capital territory with the support of a single party member or to bring political stability and strength within a coalition government, or in times of capital territory emergency, when a proper chain of command is necessary. On multiple occasions, proposals have arisen to make the post permanent, but without result. The same goes for the post of deputy prime minister at the national level.
National Capital Territory of Delhi has had only one deputy chief minister Manish Sisodia. The post has been vacant since 1 March 2023.
^This column only names the deputy chief minister's party. The union territory government he heads with chief minister may be a complex coalition of several parties and independents; these are not listed here.
