The number of Conservative MPs who can run to replace Boris Johnson could be narrowed down after changes to the party’s leadership contest rules.
The new regulations mean MPs who put themselves forward to become leader of the Conservative Party will now need the backing of 20 other Tory MPs to get on to the ballot.
Candidates will then need at least 30 votes to proceed into the next round, chairman of the 1922 Committee Sir Graham Brady said. That would be just under 10% of Tory MPs so could narrow the field further.
He added that nominations will open and close on Tuesday, the first ballot will be on Wednesday and the second ballot on Thursday with the new leader announced on 5 September.
There will be more ballots next week, probably on Monday, he said.
And if there are a large number of candidates after the nominations are in, Sir Graham said there could be hustings on Wednesday evening to help narrow down the field the following day.
So far, 11 MPs have publicly announced they want to replace the prime minister following his resignation last week.

Conservative leadership race: Penny Mordaunt latest Tory to launch bid to replace Boris Johnson as prime minister
According to Sky News’ tally, only Rishi Sunak and Penny Mordaunt have reached the 20 nominations threshold and only Mr Sunak has reached more than 30 to get through to the first round of voting.
However, many of the Conservative’s 358 MPs are yet to declare who they will be supporting.
Each time a leadership election takes place, the executive of the 1922 Committee of backbench Tory MPs determines the rules and procedures.
In 2019, an MP wishing to stand needed the support of eight other Conservative MPs to get to the first round.
After the 1922 executive held its own election on Monday afternoon, with chairman Sir Graham re-elected, they voted on the new leadership race’s timetable and rules.
By increasing the number of MPs needed to nominate a possible candidate, the length of the whole process will be made shorter.
In 2019 there were initially 10 candidates in the first ballot and six rounds of balloting were required before the final two candidates were known.
After the field is whittled down to two candidates they will face a ballot of party members based on one member one vote and the candidate who receives the most votes wins.
