Badenoch criticises Starmer for going to Cop30, claiming other leaders from 'serious' countries were staying away

Kemi Badenoch has criticised Keir Starmer for going to the Cop30 climate conference, claiming that he should have stayed in the UK to focus on domestic politics.

As Starmer delivered a speech at the summit, Badenoch said:

Keir Starmer has gone to a conference where the four biggest polluters – the US, India, China, Russia - are not there. That means that nothing serious is going to be happening.

If those four countries aren’t doing anything, Keir Starmer should focus on fixing the domestic problems we have in our country first.

Badenoch also suggested that Starmer was the “only person” from a “serious country at that conference”, where other European leaders including France’s Emmanuel Macron are also expected to attend.

Asked to respond, a Labour source said:

The prime minister has travelled to Cop with the Prince of Wales to show UK leadership on the world stage, and delivering jobs and opportunity across Britain,” they said.

The leader of the opposition should look the 400,000 UK workers in clean energy in the eye and tell them she wants to throw it all away.

And for what? Old, rusty arguments stuck in the past that she’s forced to adopt because her dwindling number of supporters demand it.
