Hong Kong Chief Executive Leung Chun-ying said on Monday that the special administrative region's first-ever blueprint for universal suffrage isn't quite finished and citizens must work together to complete it.

"We have a lot of work to do, and we will ask the people of Hong Kong to understand that this is the first time, the first time ever, in the history of Hong Kong that eligible voters will be given, each and every one of them, ... the right to vote in the universal suffrage to elect the leader of this government, and the leader of this city," Leung said at the Legislative Council on Monday.

"It is a precious offer from the National People's Congress Standing Committee. Obviously, we have work to do. I think it is an important and historical moment for Hong Kong."
