Rishi Sunak under pressure after sacking Nadhim Zahawi over tax storm

PM's judgment in question as Zahawi fails to apologise after inquiry finds breaches of ministerial code

• Analysis: a narrowing window to win back trust

Rishi Sunak has sacked the Conservative party chair, Nadhim Zahawi, for serious breaches of the ministerial code over his tax affairs, after weeks of damaging headlines undermined the prime minister's attempts to restore government integrity.

An investigation by Sunak's new ethics adviser, Sir Laurie Magnus, concluded that Zahawi had broken the rules by repeatedly failing to declare an HMRC investigation into his tax affairs, which concluded with a 5m settlement including a penalty.
