It is the third major opposition party to disband this year, ahead of the fifth anniversary of the Beijing-imposed national security law.

On the wall of the League of Social Democrats office, the Chinese characters for freedom are spelt out with court admission slips.

Members of the party take turns speaking into a microphone connected to a loudspeaker. They stand in front of a banner that reads “rather be ashes than dust”, written in Chinese. Founded close to 20 years ago, the party is known as the last protest group in Hong Kong.

“The red lines are now everywhere,” Chan Po Ying, the chair of the party, tells the BBC. “Our decision to disband was because we were facing a lot of pressure.”
