At the Downing Street lobby briefing No 10 did not deny reports that the energy price cap could rise by more than 900 in the autumn. Asked about the figure, which is a forecast from Scottish Power (see 10.58am), the prime minister's spokesperson said he could not comment on speculation. He went on:

With Ofgem, I think it's fair to say that we do expect there to be further increases later in the year. The chancellor has talked about that, and has made clear that we will look to do what we can to help with energy bills in the autumn when we know more about prices will be.

Starmer's allies fear that the next two months could be paralysed by the investigation. By saying he would resign if fined, some believe, Starmer would retain the moral high ground over Johnson, who was fined last month for a birthday gathering in 2020 and could face further fines.

There's a clear logic to it," one supporter said. It would give him something to say at the despatch box when Johnson raises it."
