In U.K., the House of Lords and the House of Commons may each adjourn at their own pleasure. In both Houses, an adjournment is effected by the adoption of the motion, 'That this House do now adjourn'. The motion to adjourn the House provides an opportunity for debate and half-an-hour is allotted for such debate. The subjects debated are of a wide range. In the House of Commons, sometimes, adjournment takes place without such a motion being carried, e.g., the Speaker may adjourn the House due to the absence of quorum or owing to grave disorder in the House.
