It's the hot ticket. In case you didn't already know, like Will's mother, Kate is a commoner.
And, so, as is the want of the bride's mother, family is thicker like blood. Apparently.
Ex-PMs Tony Blair and Gordon Brown are not invited.
Uncle Gary Goldsmith is invited.
Baroness Thatcher, John Major and David Cameron were invited. Unfortunately, the Baroness is in ill-health and declined.
