Everyone is forgetting Princess Ann, the succession was changed IIRC in case George was a girl. Ann would be ahead of Andrew in the line for the throne and could be appointed Regent if the infant George suddenly became King. Andrew is now way down the list.
SOVEREIGN
1. The Prince of Wales
2. The Duke of Cambridge
3. Prince George of Cambridge
4. Prince Henry of Wales
5. The Duke of York
6. Princess Beatrice of York
7. Princess Eugenie of York
8. The Earl of Wessex
9. Viscount Severn
10. The Lady Louise Mountbatten-Windsor

Anne doesn’t make the top ten! The list changes with births up the list.
No. Princess Ann is actually way down on the list of succession- 11th and soon to be 12th. The line falls to the Queens direct prodigy through her sons first, and then to their children, her grandchildren in rank from the eldest on down. Her youngest son, Prince Edward and his two children would come before Ann.
