Boris Johnson has embarked on a mini-reshuffle as he continued to resist calls to apologise for his controversial attack on Sir Keir Starmer over Jimmy Savile.
Chief Whip Mark Spencer, who has been criticised for his handling of discipline among MPs, is moved sideways to become Leader of the Commons.
He replaces Jacob Rees-Mogg who becomes Minister for Brexit Opportunities and Government Efficiency in the Cabinet Office.
Chris Heaton-Harris, a long time ally of Mr Johnson, takes over as his parliamentary enforcer as the new Chief Whip.
The announcements came as the Commons Speaker Sir Lindsay Hoyle delivered a fresh rebuke to Mr Johnson over his claim in the Commons last week that Sir Keir failed to prosecute Savile when he was director of public prosecutions.
