Hong Kong lawmaker challenges chief CY Leung's election

Albert Ho is challenging the election of Chief Executive CY Leung

The chairman of Hong Kong's Democratic Party has filed legal challenges against newly-installed Chief Executive CY Leung.

Albert Ho says Mr Leung, who was sworn in on Sunday amid protests, made false and misleading statements regarding illegal structures in his home.

Mr Ho was one of three candidates who sought the top post in March.

A spokesman for Mr Leung had no comment on Mr Ho's challenges.

Mr Leung, a land surveyor, has demolished the illegal structures after reports about it came out in local media. He has also apologised for it.

Mr Ho filed a judicial review asking a judge to overturn the election result, as well as an election petition.

"I just want to uphold the integrity of the system to make sure we have a fair election," Mr Ho was quoted by news agency Agence France-Presse as saying.

"Our system is already less than democratic, it's undemocratic, at least the minimum we want is that the process was held strictly in accordance with the laws."

Mr Leung was chosen as Hong Kong's new leader by a committee of 1,200 business leaders and other influential citizens mostly loyal to Beijing after an unusually turbulent campaign.

The Chinese government switched its support to him after a string of scandals hit early front runner Henry Tang, who was also said to have had an illegal basement at his home.

Mr Tang, saw his public support plummet after a newspaper reported the existence of a massive illegal basement under his home.

Mr Tang was the front runner until the basement scandal broke, says the BBC's Juliana Liu.

On Sunday, thousands participated in the annual pro-democracy Hong Kong protest and many expressed concerns about Mr Leung.
