Chief Minister of Puducherry
The chief minister of Puducherry is the chief executive of the Indian union territory of Puducherry. In accordance with the Constitution of India, the lieutenant governor is a union territory's de jure head, but de facto executive authority rests with the chief minister. Following elections to the Puducherry Legislative Assembly, the lieutenant governor usually invites the party with a majority of seats to form the government. The lieutenant governor appoints the chief minister, whose council of ministers are collectively responsible to the assembly. Given that he has the confidence of the assembly, the chief minister's term is for five years and is subject to no term limits.
Since 1963, Puducherry has had 10 chief ministers. The longest-serving and current chief minister, N. Rangasamy from the All India N.R. Congress, held the office for over sixteen years in multiple tenures. The former governor of Kerala M. O. H. Farook has the second-longest tenure, and V. Vaithilingam from the Indian National Congress has the third-longest tenure. The inaugural holder Edouard Goubert from the Indian National Congress has the shortest tenure. There have been seven instances of president's rule in Puducherry, most recently in 2021.
The current incumbent is N. Rangasamy of the All India N.R. Congress since 7 May 2021.
List
The French settlements in India were in a transition period between the de facto transfer day and the de jure transfer day. In January 1955, the government of India, by an order, renamed these four French settlements in India as the State of Pondicherry. Both these transfer days are official holidays within the union territory of Puducherry.;Enactment of the Government of Union Territories Act
On 10 May 1963, the government of India enacted the Government of Union Territories Act, 1963, which came into force on 1 July 1963. It introduced the same pattern of government that prevailed in the rest of the country, but subject to certain limitations. Under Article 239 of the Indian Constitution, the president of India appoints the lieutenant governor of Puducherry with such designation as he may specify to head the administration of the territory. The lieutenant governor appoints the chief minister. The lieutenant governor, on the advice of the chief minister, appoints the council of ministers.
Also, the representative assembly was converted into the legislative assembly of Pondicherry on 1 July 1963 as per Section 54 of the Union Territories Act, 1963, and its members were deemed to have been elected to the assembly. Thus, the first legislative assembly was formed without an election. Elections for the assembly have been held since 1964.
