Hong Kong's pro-democracy movement got a boost with about eight candidates involved in crippling protests last year winning office at district-level elections, while some veterans from both sides of the political divide suffered defeat.

The election of the Umbrella Soldiers — named after the 2014 demonstrations in which activists used umbrellas to guard against tear gas and pepper spray — reflects continued support for political change in the Chinese-ruled city.

"The paratroopers are the new force," said James Sung, a political analyst at the City University of Hong Kong, referring to candidates inspired by the Umbrella movement. "The paratroopers are a new power, a challenge to the government and the central authorities in Beijing."

Results from Sunday's polls, which saw about 900 candidates compete for 431 district council seats, where pro-Beijing parties currently hold a majority, were announced on Monday, 23 November.

"My greatest wish at this moment is to serve the community well," said Wong Chi-ken, 38, who took part in the protests and has been referred to in the local media as an Umbrella Soldier.

The election of candidates who took part in the protests now casts them in a legitimate political light, in contrast to how they were perceived by some during the demonstrations, which were deemed illegal by the Central government in Beijing.

District councillors wield little power, acting more in an advisory role in which they can push forward policies, in particular grass-roots concerns, for the government in the Chinese-controlled city to consider.

But, the poll results may provide insight into how elections for the city's powerful Legislative Council, due next year, and a controversial leadership poll in 2017 could pan out.

"The results show the Umbrella Soldiers reflect the intention or wishes of the youngsters," said political commentator Johnny Lau.

At least 40 candidates who took part in the democracy protests, or were inspired by them, ran in the elections, reported the local media.

Two democracy veterans lost their seats. Democratic Party lawmaker and heavyweight Albert Ho, who faced stiff competition in the gritty new town of Tuen Mun in the western New Territories, lost his seat. So, too, did Frederick Fung, another pan-democratic candidate who ran in the working-class district of Sham Shui Po.

On the pro-Beijing side, Chung Shu-kun of the pro-Beijing Democratic Alliance for the Betterment of Hong Kong was unseated in a surprise move after 21 years.

The mixed results from the elections, in which a record number of people voted, will not significantly change the numerical make-up of pro-democracy and pro-government groups.

The 79-day demonstrations last year, when activists streamed on to highways to demand full democracy for the former British colony, became the biggest political challenge to Beijing's Communist Party leaders in years.

The protests failed to persuade China to allow a fully democratic vote in 2017. Beijing says city voters have to choose from a list of candidates it has approved if they want a vote.

Hong Kong returned to Chinese rule in 1997 under a "one country, two systems" formula that gives it substantial autonomy and freedoms, with universal suffrage promised as an "ultimate goal".
