Nadhim Zahawi’s future threatened as Labour steps up pressure over tax affairs

Angela Rayner says Rishi Sunak should come clean about any concerns raised with No 10 about ex-chancellor and HMRC penalty

Nadhim Zahawi's political future appeared under increasing threat on Sunday night, after Labour pushed hard for answers about his tax issues and government colleagues offered little support for his plight.

After a weekend dominated by questions over the Conservative party chair's tax position, Labour signalled its intention to pin the controversy on to Rishi Sunak, demanding the prime minister explain if he knew about the issue when he appointed Zahawi to his cabinet.
