Tens of thousands of mourners are flocking to pay their respects to J Jayalalitha, one of India’s most influential and colourful politicians.
The 68-year-old chief minister of the southern state of Tamil Nadu suffered a heart attack on Sunday night and died at 23:30 local time (18:00 GMT) on Monday, Chennai’s Apollo Hospital says.
Her body, draped in the Indian flag, is on display at a large public hall.
Prime Minister Narendra Modi was among those who visited to pay tribute.
Extra police have been deployed in the state amid fears of unrest.
The extreme devotion she inspires among her supporters, many of whom refer to her as “Amma” (mother) have led to concerns that they could resort to self-harm or violence.
Earlier reports of her death, which were swiftly withdrawn, prompted scuffles between police and her supporters outside the private hospital.
However, lines have been orderly so far, despite the visible emotion among the crowds who are queuing up to catch a final glimpse of Jayalalitha. Many are openly weeping while some are beating their heads and chests.
A seven-day period of mourning has been declared in Tamil Nadu. The central government in Delhi has announced that Tuesday will be a national holiday as a mark of respect and that she will be given a funeral with full state honours.
Prime Minister Narendra Modi is due to leave for Chennai to attend the funeral which is due to be held later this evening.
He has led tributes to the former film star who served as Tamil Nadu chief minister four times. She had been receiving treatment for months.
Jayalalitha is revered by many but seen by her critics as having created a cult of personality over the years.
Tributes began to pour in for Jayalalitha as soon as her death was confirmed by Apollo, which had been treating her since 22 September.
Jayalalitha’s AIADMK party – which had earlier lowered the flag to half-mast before hoisting it up once more – also confirmed she had died, tweeting “our beloved leader, the Iron lady of India… Amma, is no more”.
“RIP Jayalalitha” has been trending on Twitter, while Facebook is also filled with elegies for a woman who is widely respected for managing to hold her own in the male-dominated world of Tamil Nadu politics.
Hundreds of people had lined the streets leading out of the hospital, despite it being long past midnight, to catch a last glimpse of the woman they called “Amma”.
As the ambulance carrying her body emerged from the main gate, a cry went up as supporters jostled forward to try and get close to the vehicle – almost breaking the police line in the process. Many of them were wailing.
Her successor as chief minister, the entire cabinet, top officials and others followed. One woman sat on the ground, distraught, her cheeks streaked with tears.
Now the action has moved to Poes Garden, the neighbourhood which has been Jayalalitha’s home for the past several decades.
The streets have been barricaded as people throng the narrow lanes for an all-night vigil.
A senior AIADMK politician, O Panneerselvam, was sworn in as chief of Tamil Nadu within hours of her death, the party’s Twitter account confirmed.
Khushboo Sundar, film actress and Congress party spokesperson, told the BBC: “It’s very painful for me. Despite our political differences, I had respected her. We were hoping against hope, none of us wanted her to lose this battle.
“She was a symbol of strength for women like me. She fought against so many odds to make a name for herself in a male-dominated profession like politics. We have a lost a great politician, and a great champion of women’s rights.”
Jayalalitha lived a dramatic life, both on screen and off.
She appeared in more than 100 films before turning her hand to politics in the early 1980s.
Jayalalitha later won control of the AIADMK from its late founder’s wife, before leading it to victory in 1991, the first of four occasions she would do so.
She was accused of corruption on several occasions, and spent two short spells in prison – most recently in 2014.
But a Karnataka high court order in 2015, which cleared her of involvement in a corruption scandal, paved the way for her return to power.
Jayalalitha’s admirers remain unbowed in their admiration for her and argue she has played a key role in the development of Tamil Nadu as one of India’s most economically influential states.
