Tens of thousands of people have begun gathering in Indian capital Delhi for a major opposition rally demanding the resignation of the country's chief election commissioner and reforms to the electoral system.
The rally, organised by the main opposition Congress party, was due to begin at noon (06:30 GMT) at the Ramlila Maidan grounds, but has yet to get under way.
Several leaders of the Congress-led INDIA opposition alliance are expected to attend, while the Gen Z-led pressure group Cockroach Janta Party (CJP) has also pledged its support.
This is the latest show of opposition anger over a voter-list revision exercise that has removed 130 million names from draft electoral rolls in India.
The Election Commission of India (ECI) says the exercise is aimed at updating the voters' list by purging names of people who have died or moved away from their registered addresses.
But opposition parties allege that the exercise - known as the Special Intensive Revision (SIR) - could benefit Prime Minister Narendra Modi's Bharatiya Janata Party (BJP) by removing eligible voters from the rolls. They accuse the Chief Election Commissioner (CEC) and the BJP of "vote chori (theft)". Both the BJP and the ECI have denied the allegations.
The controversy intensified in September when The Indian Express newspaper in its investigation, external reported that the CEC, Gyanesh Kumar, made key decisions related to the exercise without the agreement of the two other election commissioners, who had raised objections on more than a dozen occasions.
The Election Commission said differences of opinion were normal in any institution and did not affect its functioning.
But concerns over the revision process have continued, with the opposition parties, the CJP and student groups organising a number of protests in Delhi and other Indian cities.
On Saturday, opposition leaders staged a symbolic impeachment of Kumar at Congress president Mallikarjun Kharge's residence in Delhi.
The mock parliamentary session, presided over by former Lok Sabha Speaker Meira Kumar, saw leaders accuse the election chief of "conspiring to steal elections" and deliberately removing 130 million voters from electoral rolls.
Kharge, who is also the leader of the opposition in parliament's upper house, moved a symbolic motion seeking Kumar's removal, accusing him of undermining the electoral process and committing an act of "treason against the nation and the Constitution of India".
Several people whose names had been removed from electoral rolls during the revision exercise also attended the event.
The proceedings were purely symbolic and had no legal standing. Under Indian law, the chief election commissioner can only be removed through a formal parliamentary process.
Prime Minister Modi has not directly commented on the mock impeachment proceedings. However, speaking at a public rally on Friday, he said that "some people" wanted to create chaos across the country so that he could be defamed.
Later on Saturday, while addressing a separate rally, he also accused opposition parties of "abandoning their duty" and "tearing apart the dignity and boundaries of the constitution".
Last month, Congress MP and leader of the opposition Rahul Gandhi led tens of thousands of protesters in a march from Connaught Place in central Delhi to the Supreme Court, seeking the CEC's resignation.
"The march was just the trailer," a party leader told the BBC, adding that "Sunday's rally will be several times bigger than that".
Ahead of the rally, Gandhi said their protest was against "the demolition of Indian democracy", adding that "all the opposition parties and everybody who wants to come, political or non-political, is welcome".
"There is huge anger, huge emotional pain because millions are being disenfranchised," he said.
"We are all standing together because we are defending the Constitution. We are defending the idea of India. We are defending the vote, which is the expression of all Indians."
Rahul Gandhi has appealed to people to turn up in large numbers. "Don't worry about the police, don't worry about lathis [batons] - the BJP will not have the guts to try any of their antics," he wrote on X.
His comments come amid growing concerns about the policing of recent protests in the capital.
On 10 October, thousands of security personnel were deployed and large parts of the city were shut down to thwart protests called by the CJP against CEC Gyanesh Kumar.
All of the top CJP leaders were detained and many demonstrators were beaten and dragged through the streets to break up their protests. BBC reporters covering demonstrations saw, external police dragging away protesters and using batons on some of them.
The CJP has publicly backed the INDIA bloc rally, but it is unclear whether its senior leaders will attend.
