Hong Kong¡¯s pro-democracy lawmakers said Wednesday that they would resign en masse to protest Beijing¡¯s growing control over the local legislature, one of the last remaining centers of dissent in the Chinese city.

The 15 resignations were set off by a decision earlier in the day out of Beijing that forced the removal of four opposition lawmakers in Hong Kong.

The lawmakers¡¯ departure comes amid Beijing¡¯s intensifying efforts to silence Hong Kong¡¯s political opposition and to curb a vast protest movement.
