• Cop28 president says there is no science' behind demands for phase-out of fossil fuels

The British prime minister, Rishi Sunak, has been facing criticism at home for the brevity of his visit to the climate conference, having visited for less than a day. He has also been accused of hypocrisy for pushing for a phase-out of fossil fuels only weeks after approving new oil and gas licences in the North Sea.

Al Gore, the former US vice-president, said: I am not impressed with prime minister Sunak's climate policies. I think they're terrible. They're very disappointing."
