Political exchange: Secretary for Constitutional & Mainland Affairs Stephen Lam (centre) speaks at the City Forum on constitutional development.

Secretary for Constitutional & Mainland Affairs Stephen Lam says it is necessary for Hong Kong to secure progress for 2012, 2016 and 2020 Legislative Council formations.

After attending Radio Television Hong Kong's City Forum programme today, Mr Lam told reporters, under the Basic Law, Hong Kong has some say in its constitutional arrangements on electoral systems.

Noting there are now different proposals about implementing universal suffrage for forming the LegCo in 2020, Mr Lam said the future of functional constituencies is a matter which needs to be debated in the years ahead.

"What we need to do is to secure progress for 2012, 2016 and 2020 Legislative Council formations. It is necessary for us to gain progress in all of these terms of the legislature," Mr Lam said.
