Saving the planet: UK role vital if COP 26 climate talks to succeed

As PM announces Glasgow plan, much diplomatic work remains to be done

Boris Johnson's first steps on the international stage after Brexit will be to hail Britain's role in forging a new global consensus on the climate crisis - although he has not yet said who will lead that charge.

The UK will host the crunch UN climate talks, COP 26, this November in Glasgow, in what experts say is the last chance for international cooperation on the crisis. The prime minister, in launching the UK's strategy for the talks on Tuesday, stops short of promising to "get climate done", but in making his own involvement clear he will at least reassure climate activists and governments concerned at a hitherto confused and chaotic start to the UK's presidency.
