The Speaker of the House of Commons is the presiding officer of the House of Commons, the United Kingdom's lower chamber of Parliament. The current Speaker is John Bercow, who was elected on 22 June 2009, following the resignation of Michael Martin. He was returned as an MP in the 2010 general election and was re-elected as Speaker when the House sat at the start of the new Parliament on 18 May 2010.
The Speaker presides over the House's debates, determining which members may speak. The Speaker is also responsible for maintaining order during debate, and may punish members who break the rules of the House. Unlike presiding officers of legislatures in many other countries, the Speaker remains strictly non-partisan, and renounces all affiliation with his or her former political party when taking office. The Speaker does not take part in debate nor vote (except to break ties, and even then, subject to conventions that maintain his or her non-partisan status). Aside from duties relating to presiding over the House, the Speaker also performs administrative and procedural functions, and remains a constituency Member of Parliament (MP). The Speaker has the right and obligation to reside in the Parliamentary estate, near to Big Ben.
The office of Speaker is almost as old as Parliament itself. The earliest year for which a presiding officer has been identified is 1258, when Peter de Montfort presided over the Parliament held in Oxford. Early presiding officers were known by the title parlour or prolocutor. The continuous history of the office of Speaker is held to date from 1376 (see definitive studies by the late Professor JS Roskell) when Sir Peter de la Mare spoke for the commons in the "Good Parliament" as they joined leading magnates in purging the chief ministers of the Crown and the most unpopular members of the king's household. Edward III was frail and in seclusion, his prestigious eldest son, Edward the Black Prince, terminally ill. It was left to the next son, a furious John of Gaunt, to fight back. He arrested De la Mare and disgraced other leading critics. In the next, "Bad Parliament", in 1377, a cowed Commons put forward Gaunt's steward, Thomas Hungerford, as their spokesman in retracting their predecessors' mis-actions of the previous year. Gaunt evidently wanted a 'mirror-image' as his form of counter-coup and this notion, born in crisis, of one 'speaker', who quickly also became 'chairman' and organiser of the Commons' business, was recognised as valuable and took immediate root after 1376-7.
Under the new system, candidates must be nominated by at least twelve members, of whom at least three must be of a different party from the candidate. Each member may nominate no more than one candidate. The House then votes by secret ballot; an absolute majority (in the UK sense, i.e. more than 50% of the votes cast) is required for victory. If no candidate wins a majority, then the individual with the fewest votes is eliminated, as are any candidates who receive less than five percent of the votes cast. The House continues to vote, for several rounds if necessary, until one member receives the requisite majority. Then, the House votes on a formal motion to appoint the member in question to the Speakership. (In the unlikely event that this motion fails, the House must hold a fresh series of ballots on all of the nominees.)
If only one candidate is nominated, then no ballot is held, and the House proceeds directly to the motion to appoint the candidate to the Speakership. A similar procedure is used if a Speaker seeks a further term after a general election: no ballot is held, and the House immediately votes on a motion to re-elect the Speaker. If the motion to re-elect the Speaker fails, candidates are nominated, and the House proceeds with voting (as described above).
Upon the passage of the motion, the Speaker-elect is expected to show reluctance at being chosen; he or she is customarily "dragged unwillingly" by MPs to the Speaker's bench. This custom has its roots in the Speaker's original function of communicating the Commons' opinions to the monarch. Historically, the Speaker, representing the House to the Monarch, potentially faced the Monarch's anger and therefore required some persuasion to accept the post.
