Prince William may have missed memorial service because ‘one of the children had a tantrum’ claims royal expert

Queen Camilla was the most senior member of the Royal Family in attendance and was joined by Princess Anne, Prince Andrew and others at the service in St George's Chapel.

Speaking to GB News Levin said: "One person said to me that one of the children had a real tantrum and he decided to stay in. But that's the only thing I've had and I haven't had it confirmed."

The Princess of Wales also missed the service as she recovers from her "planned abdominal procedure" that took place last month.

Kensington Palace assured concerned royal fans that the last minute absence was "nothing to do with Princess Kate" and confirmed she is "progressing very well".

However, there has been speculation on whether or not this is to do with the health of the Princess.

Levin told GB News: "I think they're doing a very good job - They're keeping her very quiet.

"At one point she was going to be with her parents, then the other she was in Sandringham.

"She hasn't been out, or not that any of us have seen. But I suppose that that's what she needs to do really [stay in].

"If she's had a major operation, she needs to rest. She needs to be looked after very carefully and feel comfortable wherever she is.

"I'm sure they're looking after her very well. And there'll be lots of doctors and physios perhaps as well to help her get her mobility back, slowly but surely.

"I think she'll be very pleased about that because she is so athletic, but we don't know anything.

"It must be very stressful for all of them, and I think for the children as well.

"They need to see their mummy and be with her closely. I think the older two will be extremely kind because they realise she's not well.

"Louis will need lots of cuddling because he needs that from his mother. He wouldn't quite understand."
