Hong Kong’s most well-known student activist Joshua Wong has called for the resignation of leader Carrie Lam, after walking free from prison.
Wong became the face of the city’s 2014 pro-democracy protests which called for the city to pick its own leaders.
In the latest mass protest, organisers say two million people marched on Sunday against a controversial extradition bill.
The bill, which has now been suspended, allows extradition to mainland China.
Critics have said the legislation would expose people in Hong Kong to China’s deeply flawed justice system and lead to further erosion of the city’s judicial independence.
Much of the public anger as been directed as Ms Lam, who is pro-Beijing, and on Sunday she apologised for proposing the bill.
After diminishing in numbers overnight, large groups of protesters were seen gathering on key roads near the government headquarters again on Monday. Organisers say protests will continue until the bill is scrapped altogether.

Who is Joshua Wong?
Wong, who received two separate prison sentences in 2017 and 2018 for his part in what became known as the Umbrella Movement, walked free on Monday after serving a reduced sentence of one month.
“[Carrie Lam] is no longer qualified to be Hong Kong’s leader,” Wong told reporters at the prison. “She must take the blame and resign, be held accountable and step down.”
He also celebrated his new found freedom and called for the extradition bill to be withdrawn in a tweet on Monday.
The 22-year-old’s release is expected to further rally protesters and could put more pressure on Ms Lam, correspondents say.
The recent wave of protests in Hong Kong are reminiscent of the Umbrella Movement that took place in 2014.
The protests started in reaction to a decision made by China that it would allow direct elections in Hong Kong in 2017, but only from a list of candidates pre-approved by Beijing.

Wong and other student activists led the protests which saw thousands of people camp in the central business district for 79 days, bringing the city to a standstill.
The student activists were later convicted of unlawful assembly and jailed over an incident that helped trigger the mass protests.
Four other pro-democracy activists, including university professors and a Baptist minister, also received sentences for their part in the protests.
Why are people taking to the streets?
Organisers say almost two million people turned up for mass protests across key areas of the city on Sunday. It would be the largest protest in Hong Kong’s history if the numbers are confirmed.
The protest was mainly peaceful, with police officers reportedly holding back to allow the throngs of people to slowly pass through the city.
This is in contrast with scenes at the last major demonstration on Wednesday, which saw clashes between protesters and police that injured dozens.
Police, who used tear gas and rubber bullets, have been accused of excessive force by some rights groups.

There are fears that the extradition bill could bring Hong Kong more decisively under China’s control.
But Hong Kong officials said its courts would have the final say whether to grant extradition requests.
Ms Lam’s government had also said suspects accused of political and religious crimes would not be extradited, insisting legally binding human rights safeguards would also be in place.
