United Kingdom

Rishi Sunak is considering weakening some of the government's key green commitments in a major policy shift.

It could include delaying a ban on the sales of new petrol and diesel cars and phasing out gas boilers, multiple sources have told the BBC.

The PM is preparing to set out the changes in a speech in the coming days.

There is no suggestion that Mr Sunak is considering abandoning the legal commitment to reach net zero carbon emissions by 2050.

But he is expected to declare that other countries need to bear more of the burden of dealing with climate change.
