BORIS JOHNSON has admitted that he “doesn’t really understand climate change,” the sacked head of the COP26 climate summit revealed today.  

Claire O’Neill, who had been due to lead the United Nations climate-change conference in Glasgow later this year, launched a searing attack on the Prime Minister for failing to “show leadership and engagement” on the global emergency.

She told Radio 4’s Today programme today that Mr Johnson “could not be trusted to keep his promises” and that he had once admitted to her that he didn’t get climate change.
