Sunak effectively rules out serving in a Truss cabinet, suggesting they don’t agree on ‘big things’ – UK politics live

Tory leadership candidate says he is focused on race for No 10; energy bosses call for end to battle so new PM can tackle bills crisis

Boris Johnson is in the final fortnight of his premiership and, according to Downing Street, later today he will be meeting the chief executive, Ilan Gur, and the chair, Matt Clifford, of the new UK Advanced Research and Invention Agency (Aria). This is the body set up to fund high-risk scientific research. It is an odd choice for a legacy visit because Aria was only established because of pressure from Dominic Cummings, who was Johnson's chief adviser in No 10 until he left to become one of the most vocal, and effective, campaigners for Johnson's removal from office.

Mel Stride, the Conservative MP who chairs the Commons Treasury committee and a Rishi Sunak supporter in the leadership contest, told LBC this morning that Liz Truss would be flying blind" if she held an emergency budget in September without updated forecasts from the OBR. (See 9.27am.) He said:

Liz is coming forward with an emergency budget shortly after September 5th. And there'll be a number of very significant tax measures within that, plus some spending measures as well as yet undetermined. And at the moment the Liz camp are saying that there will not be any OBR forecasts produced at that time. And that's like flying blind. It means that you do all these dramatic things on tax etc but you don't actually know what the independent forecaster believes the impact will be on the public finances. And I think that's quite a serious situation were that to come about.
