The Prime Minister, who had told Ian Blackford that he would publish "all the details" on Wednesday, did not comment on allegations that his former adviser was in the frame for having briefed journalists about his correspondence with the tech entrepreneur, and separately with Saudi Crown Prince Mohammed Bin Salman. He told journalists: "If you think that there's anything remotely dodgy or rum or weird or sleazy about trying to secure more ventilators at a time of a national pandemic and doing everything in your power to do that, then I think you are out of your mind.

"When you're facing a pandemic and you've got 9,000 ventilators as we had - that's all we had - and, to the best of our knowledge, putting people on ventilation was the only way to help people who are really in difficulties with Covid, of course it was right to get the best of British manufacturing together as we did with the ventilator challenge." Allies of Mr Cummings have hit back at Number 10 for starting "a war they can't win", adding: "Dom doesn't care about all this stuff and they're in gov. It's like the Americans going into Vietnam - they may be able to drop big bombs but in a war of attrition, the rebel always wins." Follow the latest updates below.
