Pan-democratic lawmakers have closed ranks in initiating the impeachment of Chief Executive Leung Chun-ying, whom they accuse of deliberately lying to legislators.
At least 18 lawmakers are needed to initiate an impeachment motion, which is being proposed by "Long Hair" Leung Kwok-hung and apparently has the support of all 27 pan-democrats in the Legislative Council.
The debate is expected on January 9. The motion, however, is unlikely to survive the first hurdle, which requires a simple majority of the 70 lawmakers.
The impeachment document states that Leung intentionally gave Legco a false statement, which is a dereliction of his constitutional duty and breaches the Basic Law, which states the chief executive must be a person of integrity.
The pan-democrats also accuse Leung of misconduct in public by directing his office to make false or misleading statements in response to public inquiries on the illegal structures saga.
The document refers to Leung's remarks that he - based on his memory - did not say there were no illegal structures in his Peak residence during a Legco question-and-answer session.
The pan-democrats said this is an outright lie as Leung told journalists at his Peak home in May last year that there were no illegal structures in his home.
The pan-democrats also refer to his remarks in July that he had been negligent regarding the illegal structures and never tried to cover up the matter.
The impeachment document says Leung only revealed for the first time last month that he had built a wall to seal off a basement at his home.
"Leung Chun-ying has intentionally given false statements and lied in Legco," Leung Kwok-hung said. "This constitutes a dereliction of duty."
Ip Kwok-him, a legislator from the Democratic Alliance for the Betterment and Progress of Hong Kong, said the party will not support the motion as there is no evidence to show Leung has been in dereliction of his duties.
