CHENNAI • A former video cassette seller with close ties to Tamil Nadu's late leader will become the next chief minister of the Indian state, capping a remarkable rise for the political novice.

The ruling party in the southern state announced yesterday that Ms V.K. Sasikala would become the next leader following the resignation of the acting chief minister.

Her rise to the top office had been rumoured since December, when beloved leader Jayalalithaa Jayaram died at the age of 68, plunging the state into political uncertainty.

Ms Sasikala - a close confidante of Ms Jayalalithaa but with no previous record of public office - was soon afterwards elevated to head the ruling All India Anna Dravida Munnetra Kazhagam (AIADMK) party, paving the way to the top job.

"She is the next chief minister of Tamil Nadu. Like Amma, we wanted a strong woman leader to serve the people," party spokesman C.R. Saraswathi told Agence France-Presse, referring to Ms Jayalalithaa by her popular nickname.

"O. Panneerselvam has stepped down from the chief minister's post and he will continue to work for the party."

Mr Panneerselvam had been filling in as chief minister since October when former film star Jayalalithaa was hospitalised.

The date of Ms Sasikala's swearing-in and other formalities will be announced soon.

Although Ms Sasikala had never held any official position in the AIADMK or the state government before her election, she has long been known as "Chinnamma" (aunt) to the party because of her friendship with Ms Jayalalithaa.

The two met in the 1980s when Ms Sasikala was running a video parlour and Ms Jayalalithaa was a budding politician.

It marked the beginning of a decades-long friendship dogged by corruption scandals and intermittent spells of bad blood. In 2014, both were jailed for four years for corruption but were later acquitted.

The death of Ms Jayalalithaa on Dec 5 sparked a mass outpouring of grief across Tamil Nadu, with huge crowds lining the streets to pay tribute to her.
