Nominations for Conservative Party leader open and close today (Tuesday), and candidates require the backing of at least 20 of their colleagues to get through to the next ballot.
The first ballot will take place on Wednesday 13 July, between 1.30pm and 3.30pm, with the result being announced later that day.
Further rounds of voting will take place over the following days until just two remain by the time Parliament starts its summer recess on 21 July.
Candidates will then tour the country with a budget of £300,000 each to convince Conservative Party members to vote for them.
The winner will be announced on 5 September when Parliament returns from recess, and they will take over as the new prime minister the following day.
