It was only a few weeks ago that Oliver Dowden declared the inquiry would ‘vindicate’ the PM.
PM’s defence was, extraordinarily it now seems, that others had ‘repeatedly assured’ him that no parties breached covid guidance.
Boris Johnson, asked today about his attendance with wife Carrie, said: "All that, as you know, is the subject of a proper investigation by Sue Gray."
Sources now believe Gray will have to interview PM who is believed to have been at four of the events she's looking into.
