New Chancellor Nadhim Zahawi says it is “easy to walk away, but it is much tougher to deliver for the country” as he replaces Rishi Sunak in the Treasury.

Speaking to Sky News’ Kay Burley on his first full day in the job, he said he backed Boris Johnson and that “the team in government today is the team that will deliver”.

Both Mr Sunak and Health Secretary Sajid Javid resigned last night, saying they had lost confidence in the prime minister, and a swathe more junior ministers followed.
