Piers joined those calling for Mr Johnson’s resignation on Tuesday this week, taking to his Instagram the following morning to launch an attack on the “brazen” behaviour and “outrageous hypocrisy”, calling it a “disgusting slap in the teeth”.
The 56-year-old wrote: “REMINDER: Boris Johnson made the Queen sit alone at her husband’s funeral, just as he separated so many families in their darkest moments in this pandemic.
“Yet all the time he and his staff were brazenly ignoring their own rules with endless illegal parties at No10.
“Just outrageous hypocrisy and a disgusting slap in the teeth to everyone, like Her Majesty, who followed the rules at often great personal sacrifice,” he continued.
“That’s why this scandal is now rightly pushing the Prime Minister towards a political cliff edge. His authority has been destroyed at the altar of shameful double standards,” he added.
