Hong Kong Chief Executive John Lee voted in the territory's 'patriots-only' legislative election on Sunday.

Only 20 seats of the 90-member legislature are directly elected.

Forty other seats are chosen by a predominantly pro-Beijing election committee, with trade-based voters picking another 30 for their sectors.

All candidates must pass official vetting, including by national security authorities.

Voices of pro-democracy politicians in the legislature have disappeared after many were arrested under a 2020 national security law Beijing imposed to quell the massive protests that started in 2019.
