HONG KONG - Hong Kong Chief Executive C Y Leung Thursday reiterated the government's stand that constitutional reform should be implemented in accordance with the Basic Law and National People's Congress Standing Committee decisions.

Speaking at his Legislative Council question and answer session, Leung said many people are not clear about the Basic Law and the Sino-British Joint Declaration in defining Hong Kong's constitutional reform.

He urged the community to read the Basic Law in depth.

During the question and answer session, Leung also urged the public not to express views by unlawful actions.

He noted police arrested 511 people who illegally occupied Chater Road in Central and blocked traffic on Wednesday, saying these people had clearly expressed their views but still refused to leave after repeated advice and warnings from police.

Their actions caused a waste of police resources, he said.
