Pro-Beijing candidates swept Hong Kong's Legislative Council election on Sunday in which just one non-establishment candidate won, and pro-establishment candidates filled all 20 directly elected seats.

But the election, held without candidates from the city's major pro-democracy parties following Beijing-led electoral changes in the aftermath of the 2019 anti-government protests, recorded the lowest turnout since Hong Kong was returned to China from Britain in 1997.

A total of 153 people comprised mainly of pro-Beijing candidates ran in the election to fill the legislature's 90 seats, with only a handful of moderate and non-establishment hopefuls on the ballot.

Centrist Third Side party leader Tik Chi-yuen was the only figure elected to the revamped legislature among 14 non-establishment candidates who ran, winning a seat in the social welfare sector against two pro-establishment candidates, according to official results announced Monday.

Tik was also the only opposition-leaning figure elected to the city's powerful Election Committee in September.

Of the city's roughly 4.47 million registered voters, slightly over 1.3 million headed to the polls in the first Legislative Council election held under the new Beijing-imposed electoral system to ensure that only "patriots" govern the city.

Voter turnout for directly elected seats was 30.2 percent, compared with 58.3 percent in 2016. The record-low turnout is thought to reflect voter dissatisfaction with the lack of candidates from the city's major pro-democracy parties.

Following the election results on Monday, Hong Kong leader Carrie Lam told a press conference that she looks forward to working with the city's new legislature to resolve Hong Kong's "deep-seated problems."

Lam also praised a white paper released by the central government hours earlier that called the election "another step forward for democracy in Hong Kong" and urged the people to read it.

In the report, the central government stressed that it is for China to decide "what political and electoral systems will be adopted in Hong Kong after its return."

Lam will head to Beijing on a routine visit Monday night to speak with state leaders about the latest on Hong Kong's economic, social and political fronts, according to an official press release.

In 2016, following the 2014 Umbrella Movement that called for democratic change in the former British colony, the pro-democracy camp captured 30 of the 70 seats in the legislature.

But following the 2019 protests, which left the city in political and social turmoil, the central government called on Hong Kong to oust lawmakers deemed "unpatriotic" to rein in dissent and exclude anti-Beijing elements from the levers of power.

New Legislative Council members will serve their four-year term from Jan. 1.
