HONG KONG (Reuters) - Hong Kong’s opposition staged a final show of defiance in the legislature on Thursday before resigning to protest against the dismissal of four of their colleagues in what they see as another bid by Beijing to suppress democracy in the city.The withdrawal of the opposition from the city legislature will mean an end for what has been one of the few forums for dissent after Beijing’s imposition of national security legislation in June and coronavirus restrictions ended pro-democracy protests that began last year. Hong Kong’s Beijing-backed government expelled four opposition members from the legislature on Wednesday for endangering national security after China’s parliament gave city authorities new powers to curb dissent. The remaining 15 opposition members of the 70-seat Legislative Council, known as Legco, then said they would quit in a solidarity with their colleagues. “I suppose this is my last protest in Legco,” opposition member Lam Cheuk-ting said after unfurling a protest banner vilifying the city’s leader, Carrie Lam.
