Former health secretary Jeremy Hunt is considering a Tory leadership bid as the race to succeed Boris Johnson heats up following his dramatic resignation.
Allies claim Mr Hunt is attracting a lot of support from Tory colleagues.
Senior backbencher Tom Tugendhat and Attorney General Suella Braverman have already announced plans to stand.
Mr Johnson was forced out as Tory leader after a cabinet revolt over his leadership but wants to stay on as PM until the party chooses a successor.
Opposition parties and some Tories want him to go now – but that appears unlikely to happen and prime ministers have stayed on during leadership transitions in the past.
He has appointed a new cabinet line-up, replacing ministers that resigned in protest at his leadership, and has told them he will not ask them to make major policy decisions until a new leader is in place. was targeted out of other people related to the unnamed organisation.
