<P> 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 . </P> <P> 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 . </P> <P> Because the government and Prime Minister are effectively indirectly elected through the Commons, the terms of Parliaments and MPs do not directly apply to offices of government, though in practice these are affected by changes in Parliament . While, strictly speaking, a Prime Minister whose incumbency spans multiple Parliaments only serves one, unbroken, term of office, some writers may refer to the different Parliaments as separate terms . </P> <P> Hereditary peers and life peers retain membership of the House of Lords for life, though members can resign or be expelled . Lords Spiritual hold membership of the House of Lords until the end of their time as bishops, though a senior bishop may be made a life peer upon the end of their bishopric (e.g. George Carey, made Baron Carey of Clifton the day after he ceased being Archbishop of Canterbury). </P>
