As in most state institution the business of both Houses follows a similar daily pattern. It is noteworthy that sittings in both Houses still begin with prayers although now attendance is voluntary.
Question Time is the start of business in both chambers. Questions, known as ‘oral questions’, are asked for an hour (in Commons)/30 minutes (in Lords) Monday to Thursday after prayers.
Oral questions are tabled in advance of Question Time. MPs are to put them at least three days in advance while Lords can do so anywhere between 1 month and 24 hours. The questions are then printed in the Commons Questions Book/ the Lords Order Paper. In the House of Commons a computer determines the order in which the questions are asked.
The Prime Minister answers questions in the Commons for half an hour every Wednesday from 12pm. Questions are tabled but after the first engagements question has been asked, any other MPs who have tabled the same question are simply called to ask an untabled, supplementary question. Ministerial oral statements may be made after Question Time. The statements are usually devoted to matters of policy or government actions.
Debates on legislation, general topics of interest or issues selected by the major parties are the main business in both chambers. A debate is a formal discussion on a Bill or topic of interest or importance. At the end of the discussion the original question is repeated and the House comes to a decision – if necessary by means of a vote.
General debates without requiring the House to vote are called adjournment debates. They are held to discuss a subject or a government policy without reaching a formal decision about it.
Another way to attract a great deal of public interest to specific events or campaigns is to submit early day motions (EDMs). Although very few EDMs are actually debated they are used for reasons such as publicising the views of individual MPs.
