GMB host Piers Morgan replied, ‘This is not a private visit, if you’re the Duchess of Sussex getting a freebie at Wimbledon, in the VIP seats, watching your mate Serena Williams with the company of your friends, it’s not a private visit, you’re there as a member of the royal family.’

He went on: ‘Meghan’s got to learn she’s not a celebrity anymore, she’s the Duchess of Sussex… with the fact that taxpayers pay £2.5 million for your home refurbishment… with the fact that taxpayers pay for your security guys to be at Wimbledon… we pay for that. The deal is you’re there and then you smile.’
