The chief whip of the Labour Party oversees the whipping system in the Labour Party, and is responsible for ensuring that Labour members of Parliament (MPs) or members of the House of Lords attend and vote in Parliament of the United Kingdom in the desired way of the party leadership. The two chief whips, one in the House of Commons and one in the House of Lords, also help to organise their party's contribution to parliamentary business. The chief whip manages a team of whips, whom they may appoint from the Parliamentary Labour Party, to support the work of the whips' office.

The party leadership may allow members to have a free vote, based on their own decision, rather than party policy, which means the chief whip is not required to influence the way members vote.

The role of Chief Whip is regarded as secretive, as the Whip is concerned with the discipline of their own party's Members of Parliament.

By convention, Chief Whips do not sign early day motions or table questions to Ministers. Nor do they give media interviews in their capacity as whip.
