Least worst solution?

Should we abolish the monarchy?  With the Queen and  Prince Philip clearly in the twilight of their years, the question has raised its head again.  And yet again, whatever you think about the prospect of King Charles III, the thing you have to ask yourself is - what's the alternative?  And the only possible answer is - a President. Do we really want one if those?  Look over the pond - look at recent elections for metropolitan mayors, for police commissioners - they've all been political fights ending up with a political appointee.  Do we really want a President (here fill in a Conservative or Labour appointee)? Speaking for myself, I'll take King Charles any day,
