This includes details about seating arrangements, with royal children believed to have their own table until they are old enough to join the adults.
It is believed this is a table Prince Louis, seven, used to sit on, however it is likely he is able to join the adults now.
In 2019, Mike spoke about the celebrations on his own rugby podcast ‘The Good, The Bad & The Rugby’ and revealed: “This is the family lunch, there were seven tables so there must have been about 70 of us there.
“The kiddies have their own little one in a different room.”
Mike is believed to get on very well with his royal in-laws.
This includes his mother-in-law Princess Anne and Zara’s cousin Prince William.
Although members of the Royal Family, neither Mike or his wife Zara are working royals.
