:: Monday 10 June - Leadership candidates had to formally apply to enter the contest. Each candidate needed the backing of eight MPs in order to join the race.
A total of 10 candidates will take part in the first round of voting: Michael Gove, Matt Hancock, Mark Harper, Jeremy Hunt, Sajid Javid, Boris Johnson, Andrea Leadsom, Esther McVey, Dominic Raab and Rory Stewart.
:: 11/12 June - The candidates will take part in the first hustings event organised by the 1922 Committee.
Only Conservative MPs will be able to attend.
Conservative peers will not be able to attend the event while, despite their confidence-and-supply agreement with the Tories, DUP MPs also won't be permitted entry.
No media will be allowed in the room either.
:: 13 June - The first ballot of Tory MPs will take place.
Each MP will cast their vote - either in person or by proxy - by posting their papers into black tin boxes in Committee Room 14 in parliament.
The votes will then be counted in another room before the 1922 Committee's co-chairmen, Dame Cheryl Gillan and Charles Walker, will announce the results.
Candidates will be required to win 5% of votes (a total of 17 MPs) to move on from the first round.
If candidates don't meet the threshold, they will be eliminated.
If all candidates (or indeed no candidates) meet the threshold, the one with the lowest number of votes will be eliminated.
If no candidates meet the threshold and there is a tie at the bottom, there will be a "frank discussion" with those candidates about whether or not they agree to drop out.
If they don't, this could mean the ballot is voted on again.
:: 17 June - The candidates will take part in a second hustings event organised by the 1922 Committee.
:: 18 June - A second ballot of Tory MPs will take place with candidates this time requiring 10% of votes (33 MPs) to make it through the second round.
The same rules as the first ballot on candidates being eliminated will apply.
:: 19/20 June - A third, fourth, fifth and possibly sixth ballot of Tory MPs will be held, depending on how many rounds of voting are needed to whittle the candidates down to a final pair.
At each round, the candidate with the lowest number of votes will be eliminated.
:: 22 June - The final pair of candidates are expected to be in Birmingham to take part in the first hustings event in front of Conservative Party members.
Further hustings events are likely to be held in every region of the country.
:: 22 July - It is expected the party's grassroots members will be asked to submit their vote for their favoured candidate by 5pm on 22 July.
:: 23 July - This could see the announcement of the winning candidate by the 1922 Committee and might also be the day Theresa May visits the Queen to resign as prime minister in order to hand over to her successor.
