This article about records of members of parliament of the United Kingdom and of England includes a variety of lists of MPs by age, period and other circumstances of service, familiar sets, ethnic or religious minorities, physical attributes, and circumstances of their deaths.

Age Youngest

Prior to the Acts of Union, the youngest known person to have sat in the House of Commons of England was Christopher Monck, elected MP for Devon in 1667, "probably without a contest", at the age of 13. He sat in the House for three years, before being elevated to the House of Lords upon his father's death. He is said to have been "moderately active during his short period of membership, sitting on seven committees"."MONCK, Christopher, Earl of Torrington (1653–88)" , in B.D. Henning (ed.), The History of Parliament: the House of Commons 1660–1690, 1983

Monck was one of many members returned underage in the late seventeenth century, with around ten underage members in each of the Parliaments of 1690 and 1695, many aristocrats. In response to this, the Parliamentary Elections Act 1695 established 21 as the minimum age, although this was not reliably enforced. Until the Reform Act 1832, underage MPs were seldom unseated. For example, Charles James Fox became an MP aged 19 in 1768, and Robert Jocelyn, Viscount Jocelyn, became an MP aged 18 in 1806.

Before the general election of 2015, the youngest MP since the Reform Act 1832Before 1832, minors could be elected; precise information on those MPs is often unclear. was William Charles Wentworth-FitzWilliam, elected at Malton in the 1832 general election aged 20 and 11 months. His election, whilst theoretically illegal, was unchallenged; Malton was a pocket borough controlled by his family, and the matter was viewed as academic as he would be of full age by the time Parliament assembled.

After Wentworth-FitzWilliam, the youngest MP elected was James Dickson, who was elected as a Liberal at a by-election for the Borough of Dungannon on 25 June 1880. He was born on 19 April 1859, and so was aged 21 years 67 days. The youngest female MP was Bernadette Devlin, elected on 17 April 1969 from Mid Ulster, aged 21 years 359 days. Until 1970, the minimum age to sit in parliament was 21. In 1970, the minimum age was lowered to 18. Both records are now jointly held by Mhairi Black, who was aged 20 years and 237 days old at the time of her election to the seat of Paisley and Renfrewshire South in the 2015 general election.

Oldest The oldest serving MP whose exact dates are known was Samuel Young (1822–1918), who was MP for East Cavan from 1892 (when aged 70), until his death at the age of 96 years 63 days.

Oldest debuts Perhaps the oldest parliamentary debut of all time was that of Warren Lisle, believed born in 1695, who was elected on 7 September 1780 during that year's general election as MP for Weymouth and Melcombe Regis as locum tenens, aged reportedly 85. He stood down on 21 November to allow his kinsman, Gabriel Steward, to stand for the seat after completing his own term as mayor of the borough (when he had been the local returning officer). He died in July 1788 aged reportedly 93.

The oldest debut where a confirmed birth date is known was made by Sir Robert Pullar (born 18 February 1828) who was elected at an unopposed by-election for Perth on 12 February 1907 aged 78 years and 359 days. He retired at the January 1910 general election.

The oldest debut at a general election to the UK Parliament was possibly by Bernard Kelly (born 1808) who was elected MP for South Donegal in 1885 in the year of his 77th birthday. He died in office on 1 January 1887 aged 78.

The oldest woman at first entry to the Commons was Dr Ethel Bentham (born 5 January 1861) who was elected MP for Islington East at the 1929 general election aged 68 years and 145 days. She died in office, the first woman to do so, in 1931.

Jim Allister was the oldest MP first elected at the last general election, the 2024 general election, at age 71.
