Term of office

A term of office is the length of time a person serves in a particular elected office. In many jurisdictions there is a defined limit on how long terms of office may be before the officeholder must be subject to re-election. Some jurisdictions exercise term limits, setting a maximum number of terms an individual may hold in a particular office.

Being the origin of the Westminster system, aspects of the United Kingdom's system of government are replicated in many other countries.

The monarch serves as head of state until his or her death or abdication.

In the United Kingdom Members of Parliament (MPs) in the House of Commons are elected for the duration of the parliament. Following dissolution of the Parliament, a general election is held which consists of simultaneous elections for all seats. For most MPs this means that their terms of office are identical to the duration of the Parliament, though an individual's term may be cut short by death or resignation. An MP elected in a by-election mid-way through a Parliament, regardless of how long they have occupied the seat, is not exempt from facing re-election at the next general election.

The Septennial Act 1715 provided that a Parliament expired seven years after it had been summoned; this maximum period was reduced to five years by the Parliament Act 1911. Prior to the Fixed-term Parliaments Act 2011 parliaments had no minimum duration. Parliaments could be dissolved early by the monarch at the Prime Minister's request. Early dissolutions occurred when the make-up of Parliament made forming government impossible (as occurred in 1974), or, more commonly, when the incumbent government reasoned an early general election would improve their re-election chances (e.g. 2001). The Fixed-term Parliaments Act 2011 mandated that Parliaments should last their full five years. Early dissolution is still possible, but under much more limited circumstances.
