The same tone was struck by ex-Supreme Court Justice Lord Jonathan Sumption, who told the BBC that there was "something very strange going on" and that there was "no legal rule" warning that a factual report cannot be published in the run-up to the police probe.
"Any issues of prejudice have got to be worked through but this whole mess, this whole paralysing of politics, is being caused by the prime minister and his wrongdoing", Starmer stated.
"That's why we called for the police to investigate No 10 weeks ago and put this whole sorry business behind us, instead of waiting for Sue Gray", Carmichael said, adding that the senior civil servant's report "must be published in full, including all photos, text messages, and other evidence".
Metropolitan Police Want to 'Avoid Any Prejudice' to Their Probe
The police service added that "for the events the Met is investigating, we asked for minimal reference to be made in the Cabinet Office report".
Tuesday's announcement was followed by British Prime Minister Boris Johnson welcoming the Met's decision to conduct its own investigation because, he said, he believes "this will help to give the public the clarity it needs and help to draw a line under matters". At the same time, Johnson made it clear that he does not believe he broke the law when it comes to him taking part in several Downing Street parties.
