The representation of women in the House of Commons of the United Kingdom has been an issue in the politics of the United Kingdom at numerous points in the 20th and 21st centuries. Originally debate centred on whether women should be allowed to vote and stand for election as Members of Parliament. The Parliament (Qualification of Women) Act 1918 gave women over 21 the right to stand for election as a Member of Parliament. The United Kingdom has had three female prime ministers: Margaret Thatcher (1979–1990), Theresa May (2016–2019), and Liz Truss (2022). The publication of the book Women in the House by Elizabeth Vallance in 1979 highlighted the under-representation of women in Parliament. In more modern times concerns about the under-representation of women led the Labour Party to introduce and, decades later, abandon all-women short lists, something which was later held to breach discrimination laws.

Between 1918 and 2026, a total of 696 women have been elected as Members of the House of Commons. As of June 2026 there are 266 women in the House of Commons, the highest ever. This is an all-time high at 41%. The previous number was 220, set in 2019, which accounted for 35% of members elected or re-elected that year. Additionally, at the 2024 general election the most female Labour MPs were elected or re-elected (190 women in total) – another instance in Labour's history that this has happened, after 119 in 2017. The female member of Parliament with the longest period of continuous service is informally known as the Mother of the House, who is Diane Abbott, following the 2024 election.

Suffrage

In 1832 Henry Hunt became the first MP to raise the issue of women's suffrage in the House of Commons, followed in 1867 by John Stuart Mill. Following this attempts were made to widen the franchise in every Parliament.

Women gained the right to vote with the passing of the Representation of the People Act 1918 after World War I. This gave the vote to women over the age of 30. However, the Speakers Conference which was charged with looking into giving women the vote did not have as its terms of reference, consideration to women standing as candidates for Parliament. However, Sir Herbert Samuel, the former Liberal home secretary, moved a separate motion on 23 October 1918 to allow women to be eligible as Members of Parliament. The vote was passed by 274 to 25 and the government rushed through a bill to make it law in time for the 1918 general election. This bill did not specify any age restriction, unlike the voting bill. This later led to a number of incidents of women under the age of 30, who were not allowed to vote, standing for Parliament, notably the 27-year-old Liberal Ursula Williams standing in 1923.Cheltenham Chronicle, Gloucestershire, 8 December 1923

Records

Margaret Beckett has been the longest serving female MP in the history of the House of Commons. She was an MP for Lincoln from 10 October 1974 until 7 April 1979, and served as MP for Derby South from 9 June 1983 until 30 May 2024.

Harriet Harman has been the longest continuously serving female MP in the history of the House of Commons. She was MP for Peckham from 28 October 1982 until 1 May 1997, and served as MP for Camberwell and Peckham from 1 May 1997 to 30 May 2024. On 13 June 2017 Harman was dubbed "Mother of the House" by Prime Minister Theresa May, in recognition of her status as longest continuously serving woman MP (though she was not the longest serving MP overall, and would therefore not gain any official duties).

Female MPs with more than 25 years' service As of 2024, there are 36 women (out of a total of 693) who have served 25 years or more service in the House of Commons, either continuously or cumulatively.

In February 2018 the Electoral Reform Society reported that hundreds of seats were being effectively 'reserved' by men, holding back women's representation. Their report states that 170 seats have been held by men first elected in 2005 or before – with few opportunities for women to take those seats or selections. Broadly speaking, the longer an MP has been in Parliament, the more likely they are to be male.
