Boris Johnson warned Tories against going soft on climate change targets as he suggested that rising temperatures in Westminster may have contributed to his ousting.
The former prime minister dismissed the “nonsense” of calls to resume fracking and return to fossil fuels in response to the soaring energy prices triggered by Vladimir Putin’s invasion of Ukraine.
Mr Johnson, who was speaking on the fringes of the Cop27 climate summit in Egypt, insisted he wanted to play a supportive role to Rishi Sunak, but said he would act as the guardian of the commitments made when he was prime minister at Cop26 in Glasgow.
