 After independence , the Parliament of Singapore remained fully elected until 1984 , when amendments to the Constitution and the Parliamentary Elections Act were passed to provide for Non @-@ constituency Members of Parliament ( " NCMPs " ) . NCMPs , who are declared elected by the returning officer , consist of the best performing losers in general elections based on the percentage of votes cast . The scheme ensures that opposition representation is accounted for in the Parliament . In 1990 , yet another type of unelected Member was introduced – the Nominated Member of Parliament ( " NMP " ) . These non @-@ partisan Members were brought in to provide alternate views on policies that differed from the opinions espoused by the political parties represented in Parliament .
