HONG KONG (Reuters) - The mass resignation of Hong Kong’s opposition lawmakers leaves the pro-democracy movement with no clear option in its fight against Communist Party rulers in Beijing, one of the outgoing legislators said on Friday, but she promised not to give up.“It’s okay to lose. It’s not okay to quit,” Claudia Mo told Reuters in her office where she was packing up old campaign posters in cardboard boxes. “We will be back.” Hong Kong’s Beijing-backed government expelled four opposition members from the Legislative Council on Wednesday for endangering national security after China’s parliament gave city authorities new powers to curb dissent. The remaining opposition members quit in solidarity. Mo, of the HK First party, said the coronavirus and a sweeping national security law prevented the resumption of last year’s months-long anti-government, anti-China street protests that swept the territory.
