Scottish Secretary Alister Jack is set to stand down at the next general election.
The Tory MP has held the Dumfries and Galloway seat since 2017 before being appointed Scottish Secretary in 2019 by Prime Minister Boris Johnson – a role he kept under subsequent premiers Liz Truss and Rishi Sunak.
Mr Jack has been linked with a peerage on Mr Johnson’s resignation honours list – a position he would not be able to take up if he was still an MP.
