Party Whips ensure good communication within the party and contribute to the smooth running of the party's parliamentary machinery. The Whip lists down the speakers for each item of business and estimates the time required so that everything can be completed within schedule.

Often regarded as the disciplinarians controlling MPs in their respective parties, the Whips ensure that there are always sufficient party members in the Chamber to support the party's position and that MPs vote according to the party's line. Occasionally, he may "lift the whip" and allow MPs to vote according to their conscience.

The present Government Whip is Mr Lim Swee Say. He is assisted by two Deputy Government Whips, Mr Inderjit Singh and Dr Amy Khor.
