The Government Whip is an official in a political party whose task is to ensure party discipline in a legislature.

In carrying out his duties, the Whip lists down the speakers for each item of business and estimates the time required so that everything can be completed within schedule.

The Whip also ensures 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.
