Hong Kong disqualified four opposition members of its legislature on Wednesday for endangering security, raising the prospect of a walk-out by pro-democracy legislators who oppose what they see as Beijing's ever tighter grip on the city. The expulsions came shortly after China's parliament adopted a resolution allowing the city's executive to expel legislators deemed to be supporting Hong Kong independence, colluding with foreign forces or threatening national security, without having to go through the courts. While the city's Legislative Council is controlled by a pro-Beijing camp, the resignations of its pro-democracy lawmakers would turn it into a rubber stamp.
