Conservative MPs are throwing their hats into the ring to become the next Tory leader and prime minister, as Theresa May steps down.
Here is a list of the contenders who have said they are entering the contest, which starts on 10 June.
The deadline for nominations is Monday, 10 June. But as well as committing to standing, candidates must get enough backers to even take part.
The party recently decided to change the rules for the contest in order to speed up the process.
Candidates now need the backing of eight colleagues – previously they only required two. Some MPs have already indicated where their allegiances lie.
The order changes slightly if you look at where the support lies among party members – as shown in this survey by ConservativeHome at the end of May.
Some candidates have spent many years in senior positions, both as shadow ministers when in Opposition, or as ministers and in the Cabinet.
Those who make it to the first ballot on Thursday, 13 June, need to win at least 17 votes in the first round and 33 votes in the second to proceed further.
There will then be a series of hustings around the UK for those left in the race, followed by a postal ballot of 124,000 Conservative Party members.
The winner will be known during the week beginning 22 July.
A fool and his, or her, money are soon parted, but the bookies are also taking a guess at who is out in front.
