His adoptive mother, Paula Hudgell, said the official response put “a big beam” on his face and he went to bed “knowing he was missed”.
Having been “buzzing” when he got out of school on Wednesday, Tony said he only found out about the traffic jam and missing the garden party when he woke up from a sleep in the car.
He said he was surprised to get a personal message on the Royal Family’s page on X, formerly Twitters.
“The actual Royal Family tweeted mum and said we could go next year – I didn’t even think they would do something like that.
“They’re always busy and after the garden party they would have been tired, so I didn’t think they would do that.”
