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 office is currently held by John Bercow, who was initially 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. He was again returned as an MP in the 2015 general election and was re-elected, unopposed, as Speaker when the House sat at the start of the new Parliament on 18 May 2015.

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 as well as when leaving the office. The Speaker does not take part in debate or vote (except to break ties; and even then, the convention is that the speaker casts the tie-breaking vote according to Speaker Denison's rule). 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 Speaker's House at the Palace of Westminster.

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 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' misdoings 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.
