The Legislative Council of the Hong Kong Special Administrative Region (LegCo) is the domestic unicameral legislature of Hong Kong. It sits under China's "one country, two systems" constitutional arrangement. From 1990s to 2010s, it was the power center of Hong Kong's flawed representative democracy. The National People's Congress has full legislative power over Hong Kong. China enacted the Hong Kong national security law in 2020, removed opposition councilors, and eventually jailed them. The current Legislative Council is not democratically representative and about 40% of the seats have remained vacant since 2020.
