Prime Minister orders ethics investigation into tax affairs of Tory chairman

Rishi Sunak was in Northampton earlier to launch a mental health policy, but instead had to use the event to announce an investigation into one of his own cabinet ministers.

Revelations over Nadhim Zahawi’s HMRC penalty have raised questions over the Prime Minister’s commitment to rebuilding standards.

Meanwhile, the man who oversaw their perceived collapse, Boris Johnson, dismissed as ‘nonsense’ the accusation he helped the BBC’s chairman into the job in return for help securing a loan, now also the subject of a Whitehall probe.
