The reshuffle could see a number of prominent cabinet ministers removed from their posts, according to reports. Gavin Williamson is the first casualty of the reshuffle after confirming he has left the role of Education Secretary. Mr Johnson had been bombarded with calls from both outside and within his party to remove Mr Williamson from the Education post since his tenure began in 2019. Robert Buckland has also been confirmed as leaving his cabinet position of Justice Secretary and Lord Chancellor after holding the post since 2019. Housing Secretary Robert Jenrick is the third cabinet minister to leave his role after two years.
Foreign Secretary Dominic Raab is reported to be one of four front-line heads on the chopping board today after his disastrous handling of the Afghanistan situation.
Speculation around his removal has intensified amid his absence from the front bench in PMQs today.
Another cabinet minister reported to be on their way out is Home Secretary Priti Patel who has faced criticism for her handling of the record number of migrant boats coming over from France in recent months.
On the other side of the coin, Liz Truss has been tipped as a likely candidate for a promotion after her success in securing international trade agreements in the wake of Brexit.
Michael Gove could also be making a return to the front bench, replacing Mr Raab in the foreign office, according to insiders.
Key decisions are expected to be announced this afternoon with more changes to follow tomorrow and Friday.
