Chris Packham says world leaders have shown “incredible stupidity” by ignoring Sir David Attenborough’s climate warnings.

Sir David Attenborough, who is from Richmond, has delivered some of the most high-profile warnings on climate change in recent years.

Packham told The Big Issue politicians “forgot” the powerful messages outlined at the Cop26 conference in Glasgow.

The 64-year-old says there’s been a “total failure in their duty” to tackle global warming.
