The lawyer and TV star, known for his show Judge Rinder, weighed in on the latest revelations from Prince Harry in which he complained that Twitter had ignored his warnings about the threat of a riot at the US Capitol building and accused the British press of spreading misinformation.
The Duke and Duchess of Sussex have been giving more US interviews where Meghan Markle called British tabloids toxic and said they should come with a health warning, and Harry complained that the boss of Twitter "never got back to me" about his warning that the social media platform was being used to plan the storming of the US Capitol.
On the claims about Twitter, Rinder said: "Prince Harry! What? I don't understand at all. I mean Prince Harry, with the greatest respect in the world, what qualifies him more than anyone else at all?
"This was open source stuff. Maybe he should have got back to him but why should he have got back to him, because he's Prince Harry?"
Rinder's co-host Susanna Reid joked: "Don't worry, that seat is normally reserved for someone who's going to criticise Meghan and the royals."
Former GMB host Piers Morgan famously quit his role on the show over a row about his views on Markle's Oprah Winfrey interview in March where he stormed out of the studio.
Harry's latest complaints included that Twitter was being used to spread misinformation, but Rinder pointed out that the couple were still tied into a lucrative Netflix deal while the streaming platform went ahead with drama series The Crown which has been criticised for its portrayal of his late mother, Princess Diana.
Harry has stayed quiet on the controversy, which recently included Diana's friend Jemima Khan quitting her advisory role on The Crown after she complained that the story was not being handled "as respectfully or compassionately as I had hoped".
Rinder said: "I want to be clear, I like Meghan and Harry, her views might not be your cup of tea, fair enough.
"But my question is, if he's worried about misinformation, what about the fact him and Meghan have taken a huge deal from Netflix and the misinformation about his late mother, Lady Diana, and they've taken millions of pounds.
"How is that OK, how is that consistent, or not misinformation?"
