RISHI Sunak is preparing to replace Ben Wallace in a mini-reshuffle as soon as tomorrow.
The PM is finishing off his limited rejig of his top team, to replace the Defence Secretary who is stepping down and quitting Parliament.
Senior government sources said ministers are on standby for the imminent announcement.
The Defence Secretary is understood to have handed over a list of his preferred candidates to the PM, who is remaining tight-lipped about his new appointment.
Mr Wallace announced his shock resignation last month – after The Sun revealed he was considering his future.
