Imagine a question and stream-of-consciousness explanation for which this is the answer: the Speaker
Question: At the beginning of each new parliamentary term, the House of Commons elects one of its members as a presiding officer, known as the Speaker. If the incumbent Speaker seeks a new term, then the House may re-elect him or her merely by passing a motion; otherwise, a secret ballot is held. A Speaker-elect can not take office until he or she has been approved by the Sovereign; the granting of the royal approbation, however, is a formality. The Speaker is assisted by three Deputy Speakers, the most senior of whom holds the title of Chairman of Ways and Means. The two other Deputy Speakers are known as the First and Second Deputy Chairman of Ways and Means. These titles derive from the Committee of Ways and Means, a body over which the chairman once used to preside; even though the Committee was abolished in 1967, the traditional titles of the Deputy Speakers are still retained. The Speaker and the Deputy Speakers are always members of the House of Commons.
