How come Prince William is in line to be a future king of England and?

Prince William will never be King of England, because there hasn't been any such title since England ceased to be a kingdom centuries ago.

James VI of SCOTLAND inherited the English throne in 1603 and became the first king of the whole of Great Britain. A century later we united politically to form a single new country and kingdom.

William will the the King of the United Kingdom. Not England.

And Prince Harry is an heir to the throne, he just comes behind William and now baby George.

Prince Harry IS in line to become king of the United Kingdom. He is fourth in line after Prince Charles, Prince William and Prince George (Prince William's baby son).

Please note that England has not had a monarchy since it ceased to be a separate country in 1707.

KING OF ENGLAND..? American? NOT got the memo that the MONARCHY of THE UK is The BRITISH MONARCHY and has been for over 300 years..We BRITISH are NOT all ENGLISH....9+ million of us are from Scotland, Wales & Northern Ireland....He is in line as a son of Charles ....OUR Queen was CROWNED that of The United Kingdom Of Great Britain and Northern Ireland, Her Other Realms & Territories ect....NO SUCH TITLE as OF ENGLAND, since it is ONLY ONE of FOUR component parts of the UK....

The royal baby George is 3rd in line for the throne that's all I know?
