Women elected to the House of Commons

There are currently 264 MPs who are women.

Women have been able to stand for election as an MP since 1918, following the Parliament (Qualification of Women) Act. Since 1918, there have been 694 female MPs. 

The first female MP elected was Constance, Countess Markievicz. She won the Dublin, St Patrick’s seat in the 1918 General Election but in line with her party Sinn Féin’s abstentionist policy, she did not take her seat. The first women elected to the House of Commons who took her seat was Nancy, Viscountess Astor, who won Plymouth, Sutton at a by-election in 1919.

Download data on female MPs 

The Excel spreadsheet that you can download from this landing page provides a list of all the women who have ever been elected to the House of Commons.  

MPs are listed election by election. When more than one MP was elected on the same day, they are listed in the order in which they took the oath or affirmed (that is, in swearing-in order).

This list provides the names of the female MPs, the party they were first elected for, the constituency or constituencies they represented and the dates they sat as MPs.

Please note Sinn Féin MPs have never taken their seats in the House of Commons. They are included in the list; they are listed after the final MP to swear in at the relevant election.

Women in the 2024 Parliament 

Following the 2024 general election, 263 of the 650 seats in the House of Commons (40%) were held by female MPs. This was the highest number of women ever to sit at the same time in the House of Commons. It included 129 women elected for the first time.

It represented an increase from 220 at the 2019 general election; and from 226 at the dissolution of the 2019 Parliament.

For more information on the number of women elected in the 2024 general election and for comparisons with earlier Parliaments, see the Library Insight, 2024 general election: How many women were elected?

Since the 2024 general election one woman, Sarah Pochin, was elected. She won the Runcorn and Helsby by-election, on 1 May 2025, taking the number of women MPs to 264, the highest number ever.

As many female MPs ever as male MPs in the Chamber

Until December 2016, there had been fewer female MPs ever than there were men sitting in the House of Commons, at any one time. When Dr Caroline Johnson won the Sleaford and North Hykeham by-election on 8 December 2016, she became the 455th woman to be elected as an MP. There were 455 male MPs in the House of Commons at that time. For further information, see the Library Insight, As many women MPs (ever) as men (now).
