Shadow business secretary John Denham and shadow health secretary John Healey are to step down from the shadow cabinet, it emerged tonight.
Mr Denham and Mr Healey were reported to have resigned ahead of an expected reshuffle tomorrow by Labour leader Ed Miliband.
Mr Miliband will for the first time have a complete free hand in picking his top team following a rule change which means the shadow cabinet is no longer elected by Labour MPs.
He is expected to use the opportunity to bring in some fresh blood - although senior figures like Ed Balls, Yvette Cooper and Douglas Alexander are expected to retain their current roles.
A Labour spokesman said: "We do not comment on reshuffle speculation."
