“I think the government has to be transparent, and the work of Legco has to be transparent as well and stay close to the pulse on the ground,” Leung said, adding that he had earlier suggested to Lam about adopting the practice in Britain, in which the prime minister spent half an hour a week answering questions from parliament members.

Leung said any new arrangement was still being discussed by lawmakers, and also between Lam and her cabinet.

“As the chief executive intends to improve the relationship between the branches, I hope my colleagues will work together [towards this common goal],” Leung said, adding that it takes two hands to clap.

Since last week, the Legco committee on rules of procedure has been inviting views from legislators on whether to allow the chief executive to attend regular meetings once or twice a month for 30-minute sessions to answer lawmakers’ queries.

On show is a collection of materials including the Reunification Ordinance passed in 1997, which ensured laws previously in force in Hong Kong continue after the handover of the city from Britain to China.

Other displays include a set of traditional Kazakh costume worn by judiciary officials, presented by a delegation from the Ministry of Justice of the Republic of Kazakhstan, and a Chinese bronze relic presented by China’s Supreme People’s Court.

The exhibition is open to the public until the end of July. Admission is free.
