It's long overdue. The monarchy is a ridiculous and expensive anachronism in a supposed democracy. Have a considerably cheaper elected head of state with largely ceremonial powers -- give them no political power and cap their salary at the top of the civil service salary grade (as in Ireland) and you will rule out professional politicians.
Alas, it will not happen while large numbers of British people still like the soap opera side of the royal family, or maintain an incredibly silly, slavish devotion to the institution or to individuals within it, manifested by camping out by royal wedding routes and buying souvenir teatowels.
Surely the prospect of the queen's long-rehearsed-for death, and accession by a venal, emotionally illiterate man whose entire life has been spent waiting for his mother's demise, is enough to convince anyone that an institution where you get absolutely no say in who's next on the throne could be someone admirable, could be a Nazi sympathiser has no place in 2019?
You can't say, 'Oh, I like the monarchy because I like the queen' -- the point of it being a monarchy is that it's hereditary, and you get no say over who your head of state is.
