Hong Kong pro-democracy political party League of Social Democrats announced on Sunday it had disbanded due to immense political pressure, the latest casualty in a years-long crackdown that has already quieted much of the city’s once-vocal opposition.

Hong Kong's League of Social Democrats said on Sunday that it would disband amid "immense political pressure" from a five year-long national security crackdown, leaving the China-ruled city with no formal pro-democracy opposition presence.

Citing 'immense political pressure,' the League of Social Democrats has officially shut down, marking another step in Beijing's efforts to dismantle Hong Kong's pro-democracy movement.
