Boris Johnson struggled to explain his decision not to wear a mask while sitting next to 95-year-old environmentalist David Attenborough as he tried to put a positive spin on this week's COP26 climate summit.
"I've been wearing masks in confined spaces with people I don't normally talk to ... it's up to people to take a judgment whether they're at a reasonable distance from someone ... that's the approach we take," he said in an exclusive interview with CNN's Christiane Amanpour.
The British Prime Minister struck a somber tone on the state of the climate emergency, saying "I think you've got to be gloom and doom until we fix this thing."
Johnson hailed some of the early agreements reached at the summit, including a pact to reduce deforestation, but said the world had to be humbled in the face of the "huge" climate crisis. He also said his government was committing to reducing its reliance on coal, despite the prospect of a controversial new mine opening in northwest England.
"I don't want more coal, and our government doesn't want more coal. We'll do what we're legally able to do," Johnson said.
