The Leader of the House of Commons is the member of the Government who is responsible for organising government business in the Commons. The Leader of the House makes a weekly statement announcing the business for the week ahead.
The Leader of the House of Lords is responsible for looking after the organisation of government business and procedure in the House of Lords. He or she is appointed by the Prime Minister and is a member of the Cabinet. Since the Lord Speaker has no powers to rule on matters of procedure, the Leader advises the House on matters of procedure and order. The Leader also expresses the feelings of the House on formal occasions, such as motions of thanks or congratulation. The Leader and his or her private office are also available to assist and advise all Lords, irrespective of party.
