This came as new director of broadcasting Patrick Li Pak-chuen took office at the public broadcaster on the same day.

Wong was learned to have resigned as she was frustrated with commiting to tasks that had "overstepped her value" at RTHK.

She was also said to have acknowledged the fact that lots of colleagues around her "did not have the choice to quit" as they had been backing up the RTHK programs.

The Public and Current Affairs section Wong spearheaded, which oversees programs related to current affairs and social issues, has produced renowned programs such as "Hong Kong Connection", "LegCo Review" and "This Week".

Two RTHK producers also quitted ahead of Wong last month, including documentary "Hong Kong Stories” producer Fong Hiu-shan and satire program “Headline Daily” producer Liu Wai-ling, as they were reluctant to sign the declaration to uphold the Basic Law and pledge allegiance to the SAR government before February 18.

Wong, along with the two RTHK producers, was amongst the first batch of RTHK staff to quit after being required to sign the declaration.
