HOW DIVERSE IS THE HOUSE OF COMMONS (2024)

Following the UK general election, the UK House of Commons is more diverse than ever.

According to the Guardian, the figures are:

TOTAL: 650 MPs

Black and Minority Ethnic (BME) MPs: 89 (+23) (13.7% of the total)

Labour: 66 ethnic minority MPs (16% of all Labour MPs and 10.1% of all MPs)

Conservative 14 ethnic minority MPs (11.5% of all Conservative MPs or 2.1% of all MPs)

BME are 18% of the UK population, so they are slightly underrepresented. 

Let's assume for the sake of argument that BME was also 18% of the voters (unlikely but there is a lack of data about exact voter bloc numbers).

According to Ipsos Labour won the votes of 46% of all Black and Minority Ethnic (BME) voters, while 17% voted for the Conservatives and 12% for the Lib Dems.

46% of 18% (of the total vote) is 8.28%, which is the Labour BME vote as a percentage of the total vote. As Labour got 33.7% of the total vote, this means that 25.42% of the vote was "Labour and White."

17% of 18% is 3.06%, which is the Conservative BME vote as a % of the total vote. As the Conservatives got 23.7% of the total vote, 20.64% of the vote was "Conservative and White."

So the 8.28% of the total vote that is "BME and Labour" produces 10.1% of the total MPs who are Labour and BME. Meanwhile the 3.06% of the total vote that is BME and Conservative produces 2.1% of the total MPs who are Conservative and BME.

Labour is thus overrepresenting ethnics, while the Conservative Party is underrepresenting them.
