The third-term Chief Executive may need to invite more members of political parties to join the Executive Council and to be candidates for nomination as Government Secretaries.

This was the message from Secretary for Constitutional Affairs Stephen Lam after a radio talk show this morning.

In the long run, political talent in Hong Kong can come from three main sources - people who have political backgrounds, government colleagues who have served in the civil service previously, and those in the private sector who have an interest in rendering public service, Mr Lam said.

These are the three types of political talent which future Chief Executives would need to consider, he added.

"It's just a matter of rolling things forward. And, it is, I think, a necessary consideration for any future Chief Executive to determine how best he or she can cooperate with political parties both within the Legislative Council and in the wider community," Mr Lam said.

Speaking on the method of the selection of the third-term Chief Executive, Mr Lam said his bureau is doing research and analysis.

"Basically, I do not think there is a major problem. However, there are some legal technicalities and aspects which I have to deal with before I can give everybody a final answer.
