A number of Wednesday’s papers lead with the news that former prime minister Boris Johnson – who last year was fined for parties held in Downing Street during the coronavirus lockdown – has been referred to the police by the Cabinet Office over claims he also hosted events at Chequers, the prime ministerial residence in Buckinghamshire.
