Appointed by the Prime Minister, the Leader of the House is responsible for the arrangement of Government business and the legislative programme of Parliament. The Leader also proposes appropriate actions to be taken on any procedural matters arising in Parliament.
The Leader of the House moves procedural motions relating to the business of the House during sittings, such as to extend the times of sittings beyond the usual time as set out in the Standing Orders.
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, the Party Whip may "lift the whip" and allow MPs to vote according to their conscience.
