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.
