Hong Kong leader Carrie Lam has said she will withdraw the controversial extradition bill which triggered months of protests.
The proposal, introduced in April, would have allowed criminal suspects to be extradited to mainland China.
The bill was suspended in June when Ms Lam called it “dead”, but she stopped short of withdrawing it.
Full withdrawal is one of five key demands of protesters, who are also calling for full democratic rights.
On Monday, Ms Lam was heard on leaked audio tapes blaming herself for igniting Hong Kong’s political crisis, and saying it was unforgiveable of her to have caused such huge havoc.
The extradition bill quickly drew criticism after being unveiled in April. Opponents said it would undermine Hong Kong’s legal freedoms and might be used to intimidate or silence critics of Beijing.
Hong Kong is now in its 14th successive week of demonstrations, and saw fresh violence between police and activists last weekend.
Ahead of Ms Lam’s announcement, leading pro-democracy activist Joshua Wong said the withdrawal of the bill would be “too little too late”.
