The Mayor of London, Sadiq Khan, said: “The findings of the Sue Gray report today confirm what many of us had long suspected - the abject failure of leadership and judgement at the heart of Government.
“At a time when millions of Londoners were being asked to make huge sacrifices – to stay away from loved ones and forgo funerals - No 10 and the cabinet office consistently and flagrantly held the public, and the rules they had been told to follow, in contempt.
“The British public deserve better and the PM should now demonstrate accountability for this culture of impunity which took place on his own doorstep and under his own roof."
