Who are the Conservative Party MPs who will choose the next Prime Minister?

Conservative MPs now vote five times to narrow the field of their leadership contest to just two candidates, with Rishi Sunak and Liz Truss currently competing and the winner to replace Boris Johnson as Prime Minister.

Unlike previous rounds, however, this stage has a wider electorate: Conservative members will be able to vote on which of the two will become the leader of the party.

We can expect to see the tenor of the race change as candidates try to appeal beyond the parliamentary party and to members at large. But who are these people ?

How many?

We don't know how many Conservative Party members there are, as the party has stopped publishing official figures.

But we know there were at least 160,000 in the party when Mr Johnson became Prime Minister.

That's because that's the number of people eligible to run in the final leadership race in 2019. The party says that number is likely to be higher this time.

Where do they live?

A useful resource for understanding party membership is the Economic and Social Research Council's Party Members Project, led by academics Tim Bale, Paul Webb and Monica Poletti.
