Is Charles III a closet republican?

I think if you injected King Charles with sodium penathol and asked him, he'd say the UK should renounce the six Counties and Ireland should reunite immediately.

In fact, you probably wouldn't even need the drug.

Charles has been in Ireland way more than his public diary would suggest, he often came privately for holidays with friends he has, mostly in Munster.

He loves it here, for the peace, the privacy, the fact people just leave well known folk alone and that he is treated as just another bloke. Plus he loves the outdoors and nature. Its just like Scotland, but with easier hills and nobody bowing.

He and Michael D are also thick as thieves.

I'd go so far as to say if Charles hadn't been the heir, he'd probably be living in Mountbatten's old house in Classiebawn for donkey's years now.

A large part of British history was always about the Parliament and the Monarch and who can decide and do what. This goes back to the English civil war, the beheading of Charles the 1st, Cromwell, The Restauration and later on the Glorious Revolution of 1688.

The King has no right to impose taxes and impose laws and can also not declare war on anybody, even though he's the monarch.

In a nutshell, he can't do very much, other than represent, nice neutral speeches and wreath laying ceremonies on various occasions such as Remembrance Day.

He doesn't even have a passport, neither a driver's license and only travels overseas if he's invited.

Also, imagine, you're living right in central London and can't go out for a beer to a pub or any other meal on your own, or a movie or a theatre or opera performance.

Didn't he say he'd serve for life?

UK has not (yet) left the ECHR, it's nothing to do with the EU.

No. The hardliner NI Unionists have, as Malcolm Tucker would say, all the charm of a rotting teddy bear by a graveside. They're probably a bit embarrassing to him and his title that the most ardent pro-Monarchy fanatics are head-bangers who hate gays and think the world is about 6 thousand years old. They're obviously clowns and it's a blow to the ego to know you're best supported by clowns.

But he has shown no evidence that he doubts the role of the Monarchy. I think the Monarchy is a complete joke that old British people play on themselves. It doesn't so much harm nowadays though so I say leave them to enjoy it.

That doesn't mean death. In the past, it has been interpreted as loss of possession of the monarch's faculties.

If the soundness of the King's mind was ever in doubt, the Government and the Lord Chamberlain could take a decision, confirmed by an Act of Parliament, to name the Prince of Wales as Prince Regent until the natural death of the King and his own formal accession.

It last occurred when 'Mad' King George III was bypassed in 1811 and his son, later George IV, ruled as Regent until 1820.

Apologies if you're joking. But the OP presumably means to ask if Charles is republican on the quearionnof whether the UK should have a Monarchy or not, whether it should be a Monarchy or a Republic. Not whether NI should belong as part of the UK or ROI.
