Beijing-backed Carrie Lam elected as Chief Executive amid pro-democracy protests.

A Beijing-backed civil servant, Carrie Lam, was chosen to be Hong Kong’s next leader on Sunday amid accusations that Beijing is meddling and denying the financial hub a more populist leader perhaps better able to defuse the political tension.

The majority of the China-ruled city’s 7.3 million people have no say in deciding their leader, who is chosen from among several candidates by a 1,200-person “election committee” stacked with pro-Beijing and pro-establishment loyalists.

Healing the divide

Ms. Lam, who will become Hong Kong’s first woman Chief Executive when she takes office on July 1, won 777 votes compared with 365 for her closest rival, former financial secretary John Tsang, who polls show is more popular.

There were several invalid protest ballots, including one that carried an obscenity.

“Hong Kong, our home, is suffering from quite a serious divisiveness,” Ms. Lam said in a victory speech.

“My priority will be to heal the divide and to ease the frustration, and to unite our society to move forward.”

Ms. Lam also pledged to follow through on election promises including introducing a “two-tier” profits tax, reducing tax to spur research and development, tackling the high cost of housing by increasing land supply and boosting education spending. She also promised to defend the rule of law and freedom of expression as integral to underpinning prosperity. “Hong Kong needs new thinking,” she said. Some scuffles broke out outside the voting centre between protesters and police, who used metal barricades to keep the demonstrations well away.

The activists denounced Beijing’s “interference” amid widespread reports of lobbying of voters to back Ms. Lam, rather than Mr. Tsang.

1 country, 2 systems

Some protesters chanted “I want universal suffrage” and unfurled yellow umbrellas, a symbol of the civil disobedience “umbrella movement”, when the result was announced.

Hundreds of Ms. Lam’s supporters waved Chinese flags and cheered inside and outside the venue after her win.

Since Hong Kong returned to Chinese rule in 1997, Beijing has gradually increased control over it even though it promised wide-ranging freedoms and autonomy not allowed on the mainland under the formula of “one country, two systems”, along with an undated promise of universal suffrage.

Many, including opposition democrats, fear Ms. Lam will stick to the tough policies of staunchly pro-Beijing incumbent Leung Chun-ying, who ordered the firing of tear-gas on pro-democracy protesters in 2014 and who was not seen to be defending Hong Kong’s autonomy and core values.

All of Hong Kong’s three other post-handover leaders have struggled to balance the demands of China’s stability-obsessed Communist Party leaders, with the wish of many residents to preserve the global financial hub's liberal values and rule of law that have long underpinned its economic success.

China's Hong Kong and Macau Affairs Office congratulated Lam, saying she should not disappoint the people and should seek to “comprehensively unite all sectors of society”, strengthen development, and “work hard to forge a new situation”, the official Xinhua news agency said.
