Theresa May has been warned by sacked ministers that she must promote them back into Government within a year or face “trouble” in Parliament.

Senior Tories dismissed by the Prime Minister in the summer have privately warned their “loyalty” only stretches so far after being sent to the backbenches.

Some are ready to increasingly rebel over Mrs May’s grammar schools ban and Brexit priorities unless they are put back on the Government payroll soon.

The ultimatum, made in conversations with The Sunday Telegraph, is designed to make sure Mrs May makes good on indications there is a route back to the Government for those who behave.
