Rishi Sunak is to fill his No 10 with ex-Treasury staffers and long-term loyalists, including a high-flying protege of Dominic Cummings as his chief of staff.

Insiders expect a top job for Liam Booth-Smith, who ran Sunak’s leadership campaign and was his most senior aide at the Treasury, though technically his job title was head of the joint No 10 and No 11 economic unit.
