Commercial-sector lawmaker Jeffrey Lam said on Monday he is hoping to provide more opportunities to the younger generation by standing down in the upcoming election.
The 73-year-old is among at least 10 incumbents who have decided not to seek re-election for December's Legislative Council polls.
Lam, who announced his decision on Sunday, said there was no need to focus on age when asked about speculation that an age limit of 70 is in the air for legislators.
"There are many different groups in Hong Kong. No one is talking about this," he said.
"I think the most important thing is to have a suitable candidate who can handle different types of work.
"Having more new faces and new voices at the Legislative Council, and bringing new changes, is what everyone is glad to see.
"I always believe young people are our future."
Transport-sector lawmaker Frankie Yick of the Liberal Party was the latest addition to a wave of legislators signalling their intention to not run in the upcoming polls. He made the announcement on Monday.
Legco president Andrew Leung was the first to announce he would not stand for re-election.
Others included Ma Fung-kwok from the Election Committee constituency; catering-sector lawmaker Tommy Cheung; Chan Kin-por, who's representing the insurance industry; Third Side's Tik Chi-yuen; the DAB's Kennedy Wong; Gary Zhang of New Prospect for Hong Kong; and Professional Power's Connie Lam.
