Harry and Meghan’s children will definitely not be there.
Assuming the senior Sussexes do make the trip over, they’ll be a minor part of the festivities.
Harry will not participate in the ceremony, but then, neither will most of the royal family.

“One said to me, ‘I hope they’ll be seated in Iceland.'”
That may be somewhat accurate.

This was only one of many waysthe royal family has snubbed Harry and Meghan since Megxit.
