HONG KONG (Reuters) - Hong Kong's pro-democracy camp failed on Monday to regain some veto power in the city's legislature in a pivotal by-election, struggling to draw what they hoped would be protest votes against creeping control from Communist Party rulers in Beijing.
The democrats won only two of four seats up for grabs, with the opposition now left one seat short from having the power to block most bills in the 70-seat legislative chamber.
The by-election marked the first time the democratic camp has lost its long standing veto power via the ballot box, raising fresh questions over the future of the struggle for democracy and autonomy in the freest city in greater China.
The polls were triggered when six pro-democracy lawmakers were ousted from public office over invalid oaths of office in a move that critics said was politically motivated - a move that cost them their veto power. The two remaining seats have yet to be filled.
Sunday's polls coincided with the historic vote in China's parliament that removed president Xi Jinping's term limits, giving him the right to stay in office indefinitely.
During a visit to the city last July, Xi warned Beijing wouldn't tolerate any challenge to its authority.
After more than a century of British colonial rule, Hong Kong returned to China in 1997 under a "one country, two systems" formula guaranteeing it a high degree of autonomy and the promise of eventual universal suffrage.
Over the past two decades however, tensions have simmered and occasionally boiled over with activists pushing in vain for full democracy amidst opposition from Beijing.
While some democrats had made appeals for votes to redress the injustice of the disqualifications and to safeguard the city's autonomy, they struggled to overturn what some saw as voter malaise.
A turnout of 43 percent, far less than the 58 percent for full legislative council polls two years ago, suggested votes could have become fatigued with the democrats struggle.
"The pan-democrats have paid a huge price due to the recent political storms these few years," said Au Nok-hin who won one seat for the democrats.
Au was running in place of Agnes Chow, who was barred by authorities from running in a move that drew international criticism.
Democratic candidate Edward Yiu, one of the six disqualified lawmakers, failed in his comeback bid, losing out narrowly to a pro-Beijing candidate.
The loss of Yiu's seat meant the democrats failed to regain veto power over most bills in the legislature, which could effectively become a rubber-stamp parliament not unlike Beijing's National People's Congress.
"This will have an impact on how we supervise the government," said Charles Mok, a pro-democracy lawmaker, who said a "fundamental" power had been lost.
The opposition, however, still has a chance to claw back that veto power when the by-elections are held for the remaining two seats vacated by the disqualifications - though no date for those contests has been set.
"The space for expression is getting narrower for Hong Kong," said voter Candy Chan, a 24-year-old fashion designer. "While I haven't completely lost hope, my feeling is things will gradually get worse."
