Rishi Sunak has been urged to scrap the ban on new petrol and diesel cars scheduled for 2030 after a surprise Tory by-election win was driven by a green scheme revolt.

While the Tories fell to substantial defeats in the Selby and Ainsty and Somerton and Frome polls, their victory in Boris Johnson’s former constituency of Uxbridge and South Ruislip came after a campaign centred on opposing the expansion of Sadiq Khan’s ultra-low emissions zone (Ulez).
