Parliament is taking a mid-term break at a time when the country is in transition, and adjusting to new domestic needs while navigating an uncertain international environment, Prime Minister Lee Hsien Loong said on Tuesday.

The House has gone into recess and will reconvene on May 16, when President Tony Tan Keng Yam will give his address which will set out the Government's key priorities for its second term until the next election, widely expected to be held in 2016.

After the President's address, MPs will then discuss strategies for creating a brighter future and a better Singapore for all, PM Lee added.

Writing on Facebook, he said Parliament had been busy in the two-and-a-half years since the last General Election in 2011.

"We have had vigorous and valuable debates on our White Papers on Ministerial Salaries and Population. We have passed Budgets that include major economic and social policies, including the Pioneer Generation Package, GST Vouchers, and Workfare enhancements," PM Lee wrote.

"MPs have filed many questions to obtain information, press for actions, and solve their voters' problems."

Parliament is where most important national issues are debated and while Singapore's sittings are "not as fiery as some other legislatures", the Government's duty is to "manage affairs responsibly and soberly, and not to create entertainment and excitement", he said.
