I have always been a monarchist on balance as I think the pomp adds value to the country. However, looking at some of their shenanigans, I think that their existence in its current form is harder to justify. If the UK breaks up, then I can see huge changes taking place.

I think a majority still support them but feel major change will need to happen if they are to survive as a firm.
