The term "Member of Parliament" by modern convention means a member of the House of Commons. These members may, and almost invariably do, use the post-nominal letters "MP". The annual salary of each member is £74,962, effective from 1 April 2016. Members may also receive additional salaries for other offices they hold (for instance, the Speakership). Most members also claim for various office expenses (staff costs, postage, travelling, etc.) and, in the case of members for seats outside London, for the costs of maintaining a home in the capital.
