Rishi Sunak has got into a public slanging match with Zac Goldsmith after he quit with a brutal attack on the government.
In an extraordinary resignation letter, the Tory peer accused the Prime Minister of being "simply uninterested" in environmental issues and damaging the country's reputation on the world stage.
But Mr Sunak hit back as he accused Lord Goldsmith of leaving government because he would not apologise for a tweet attacking the investigation into Boris Johnson's Partygate lies.
