Is it Andorra? One of their two heads of state is French president Emmanuel Macron.

I'm not sure he is a prince though...
Yes it is Andorra. The French President becomes a prince of Andorra for the period of his (or her, one day) presidency. The UK is a unitary parliamentary constitutional monarchy. Andorra is a unitary parliamentary constitutional semi-theocratic elective diarchy. It has joint heads of state, the President of France and the Bishop of Urgell, currently Joan-Enric Vives i Sicília, which is why it is semi-theocratic.
 
Thinking about that again is it Lake Bassenthwaite ? Depends on the definition used - all the others have another name for a body of water in their names such as Coniston Water or Windermere (which would be adapted from the German word for a sea).
