Hong Kong’s pro-democracy parties won a third of the seats up for grabs in the former British colony’s legislative elections on Sunday.
They picked up a less-than-expected 27 seats on the 70-seat legislative council, giving them a possible veto over the pro-Beijing government’s future policies.
Albert Ho, the leader of the Democratic Party, stepped down from his role after its poor showing.
The vote follows weeks of protests against a now-axed policy to teach patriotism classes in school.
Activists say it shows Beijing’s increasing willingness to encroach on Hong Kong’s autonomy.
Britain handed Hong Kong back to China 15 years ago.
