Don't need opposition MPs?

The main function of the parliament is legislative i.e. the making of laws. Opposition MPs are needed to provide a robust argument to any proposed legislation. Ideally, the opposition should form at least 1/3 of the house so that it is not so easy for the ruling party to pass any new legislation.

Question time is just an accompanying function of the House. Opposition MPs are more free to raise questions, especially those on the policies of the government. Furthermore, what is said in Parliament carries more weight as it is the privilege of only the elected few. Ruling party MPs are not allowed to question government policies.

In Singapore, the number of opposition MPs is very small. The government there has resorted to apoint nominated MPs so as to have a more lively debate in the House.
