Steve Barclay has been appointed as health secretary, Downing Street has announced.
It comes after Sajid Javid’s shock resignation, which was followed by Chancellor Rishi Sunak.
The two senior cabinet ministers spectacularly quit earlier on Tuesday evening as Boris Johnson battled to remain in Number 10 amid growing questions over his handling of the row over disgraced deputy chief whip Chris Pincher’s conduct.
Mr Barclay was previously the chancellor of the Duchy of Lancaster and chief of staff for Downing Street.
