Wong Tai Sin District Council

During the 2003 District Council elections, Kwok ran in Ching On constituency of Wong Tai Sin District Council, but was not elected.^[3]

Eastern District Council

Kwok ran for election in Provident constituency of the Eastern District Council during the 2007 District Council elections. He was elected with 2,527 votes.^[4] He ran uncontested during the 2011 election and 2015 election, retaining his seat by default.^[5][6]

He was reelected in the 2019 election with 3,229 votes, narrowly beating second-place candidate Duncann Chan by 48 votes.^[7]

Legislative Council

The pro-Beijing Federation of Trade Unions (FTU) selects members for two Legislative Council seats comprising the Labour functional constituency. Kwok, holding one of the FTU seats, was elected uncontested during the 2012 election.^[8]

During the 2016 LegCo election, he ran for a seat in the Hong Kong Island geographic constituency and was elected with 45,925 votes, or 12.2 per cent of the total votes cast.^[9]

Disqualification of localist lawmakers

Kwok has advocated removing localist legislators from office. In November 2016, he urged the government to challenge the seat of Lau Siu-lai, who was elected during that year's election, on the basis that she read her swearing-in oath very slowly as a form of protest.^[10][11] The government later launched legal action against Lau and other democratically elected legislators, successfully removing them from office.

Attitude toward homeless people

In November 2017, Kwok was criticised by netizens and anti-poverty activists after expressing a callous attitude toward street sleepers. He made a post on his Facebook page boasting that a footbridge in his district (Provident constituency), on Tong Shui Road, had been cleared of homeless people (and their belongings) on 23 November 2017. The Facebook post included an animated GIF, displaying the clean-up, with the words "all clean". The footbridge was popular with street sleepers as it is redundant to a crosswalk at street level and therefore sees little foot traffic. An anti-poverty activist said that Kwok's post was reminiscent of the concurrent purge of Beijing's so-called "low-end population" that has drawn international attention.^[12]

In response to the controversy, Kwok responded that the street sleepers posed a health and safety issue, and that he had received complaints about the footbridge from his constituents. He stated that homeless people should stay in shelters or apply for public housing. In response to this, some social workers responded that shelters had time limits and did not constitute a long-term housing solution, and the process for acquiring a public housing unit is not easy.^[13]

Legislative Council assault allegation

On 8 May 2020, a meeting of the House Committee of the Legislative Council became chaotic due to controversy between the pro-democracy and pro-Beijing camps over the election of the new committee chair. Live footage filmed during the meeting by Radio Television Hong Kong showed Kwok grabbing Raymond Chan Chi-chuen by the collar and dragging him to the floor. Chan was sent to hospital, where he was diagnosed with a spinal disc herniation.^[14]

On 11 May, Chan announced that he had filed a report to the police, accusing Kwok of assault. Chan said he would also launch a crowdfunding campaign to fund private prosecution against Kwok, as he stated that he had little faith in the police nor the Department of Justice.^[15][16] Chan launched a crowdfunding campaign to pay for the prosecution, which exceeded its HK$1 million goal within hours. Kwok defended his actions, stating that he was trying to protect LegCo security guards.^[17] Chan launched a private prosecution against Kwok around three weeks after the encounter. On 6 November, Secretary for Justice intervened and halted the case in the hearing 3 days later.^[18]

Attitude toward LGBT community

On 22 November 2018, Kwok voted against a legislative motion that called for the government to explore legal unions for same-sex couples in Hong Kong. He was among the 27 lawmakers to oppose the motion, and this majority overruled the 24 favourable votes.^[19]

On 27 July 2020, Kwok faced criticism for ridiculing lawmaker Raymond Chan based on his sexual orientation.^[20] In a Facebook live broadcast, Kwok referred to Chan as "Mr. Chrysanthemum" and his advocates as "chrysanthemum groupies". The chrysanthemum flower is considered a common euphemism for anus in Cantonese lexicon.^[21] Chan condemned the derogatory terminology used to mock and discriminate against the gay community.^[22][23] LGBT singer Anthony Wong Yiu-ming stated that Kwok's stance represented outdated views on homosexuality from the pro-Beijing faction.^[21] Politician Tiffany Yuen was critical of Kwok's homophobic language and demanded an immediate apology.^[24] On the next day, Kwok continued his usage of "Mr. Chrysanthemum" in his live broadcast.^[22]

Driving while participating in LegCo video conference

On 14 January 2021, Kwok participated in a video conference of the Legislative Council's Panel on Housing, where he was suspected to have been driving while in the meeting, potentially violating the Road Traffic Ordinance.^[25][26]

Falsely claimed The Guardian is a paper for WHO

During the debate on the Motion of Thanks for Chief Executive's 2020 Policy Address on 21 January 2021, Kwok falsely claimed The Guardian (衛報) is a paper for WHO (世衛).^[27]

Birthday party

On 5 January 2022, Carrie Lam announced new warnings and restrictions against social gathering due to potential COVID-19 outbreaks.^[28] One day later, it was discovered that Kwok attended a birthday party hosted by Witman Hung Wai-man, with 222 guests.^[29][30][31] At least one guest tested positive with COVID-19, causing all guests to be quarantined.^[31] Kwok later claimed that the real issue was not the party, but the government's policy of allowing aircrew from Cathay Pacific to quarantine at home, saying "I wonder if society should be spending time chasing this party while ignoring the whole anti-epidemic loophole".^[32]

COVID-19

In December 2022, Kwok was tested positive for COVID-19.^[33][34]

District Councils

In May 2023, after District Councils had a reduction in democratically elected seats, Kwok said that public opinion suggested "we do not trust in the public," and argued against the public opinion, saying "of course, we know this is a misleading and wrong concept."^[35]
