Downing Street has announced that the 14th secretary to the cabinet and head of the civil service will be Sir Chris Wormald. He will succeed Simon Case when the latter stands down after four years on 16 December. Wormald, 56, has been permanent secretary at the Department of Health and Social Care for eight and a half years, before which he was the top official at the Department for Education for four years – a true Whitehall veteran.
