Sir Geoffrey Clifton-Brown is among a group of MPs set to make a decision which could lead to the end of Prime Minister Boris Johnson's premiership.
The MP for the Cotswolds is treasurer of the 1922 Committee, who are meeting today and could decide whether to change their rules on time limits for no-confidence votes.
Sir Geoffrey voted against the Prime Minister last month, saying he felt the country needed a change in direction.

But as Boris Johnson narrowly won the vote, the rules as they currently stand would make him safe from another no-confidence vote for a year.
However, the 1922 Committee are expected to decide today whether to change those rules. If they do, another vote could take place as early as next week.
Commenting on recent government resignations, including chancellor Rishi Sunak and health secretary Sajid Javid, Sir Geoffrey said: "I did vote for no confidence in the Prime Minister on the 6 June 2022, I came to the conclusion that he had lost the trust of too many constituents, and I continue to be concerned about the lack of strategic vision for the country.
"As an officer of the 1922 Committee who may be involved in a critical decision of whether or not to change the rules on time limits for no-confidence votes in the Prime Minister, I will not be commenting further at this present time."
The resignations have followed the Prime Minister's apology over his appointment of scandal-hit former deputy chief whip Chris Pincher.
The Prime Minister acknowledged he should have sacked Mr Pincher when he was found to have behaved inappropriately when he was a Foreign Office minister in 2019, but was instead appointed to other government roles.
Mr Pincher quit as deputy chief whip last week following claims that he groped two men.
Earlier this week, Sir Geoffrey Clifton-Brown said the situation had been handled by the Prime Minister and the party in 'a very clunky way'.
