The Party Whip ensures good communication within the party and contributes to the smooth running of the party's parliamentary machinery. The Whip lists the speaking MPs for each item of business and estimates the time required so that a sitting can be completed within schedule.
Often regarded as the disciplinarian in his respective party, the Whip ensures that there are 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 Chan Chun Sing. He is assisted by two Deputy Government Whips, Ms Sim Ann and Mr Sam Tan.
