Quoting the Queen’s husband, he penned: “‘Give TV interviews, by all means,’ Philip said. ‘But don’t talk about yourself.’”

Piers then shared the Duke’s reported opinions on Meghan and Harry’s decision to speak about their experiences as senior royals in their interview with Oprah.

Quoting Philip’s biographer and long-time friend, Gyles Brandreth, he continued in his latest MailOnline column: “Gyles Brandreth said the Duke thought Meghan and Harry’s decision to grant their friend Ms Winfrey a lengthy prime-time US TV audience was ‘madness’ and ‘no good would come of it.’ 

Ofcom had received a record-breaking number of complaints before ITV bosses held discussions with Piers about disbelieving Meghan in an on-air rant.

Piers recently told Tucker Carlson on FOX News while discussing his GMB departure: “I was hired by ITV to do the morning show because they were struggling with the ratings, they wanted me to shake things up… I was a highly opinionated person and they knew that. 

“Over five years we trebled the ratings and the last day ironically was the first day we beat the BBC.

“Instead I was corralled into a position that ‘You’ve got to apologise… or your position is untenable.'”
