I think all we normally get for that is car shots as it's a 'private event'
I wonder if Meghan and Harry will go though? It's a private event and I know they aren't spending Christmas Day with his family and are on a break but that kind of falls into the grey area of not public but not private either.
I think if they miss that and then obviously are missing Christmas that will be the clearest statement to how things are in the family we get!
