I think more radical changes to the constitution are the last thing this country needs.
After COVID and Brexit, we desperately need a bit of stability (although a change of government would be pretty welcome).
Trump-style corruption is what I see when I consider the idea of a republic. I think Charles and William will be much more hands-on when it comes to the duties of managing parliament, and wouldn't just accept the same level of corruption. Plenty of reports suggest they'll manage things far more robustly - which given the shenanigans of Boris and his blatant lies in recent years is no bad thing.
I understand the objections to the monarchy but unless you're planning on wiping out all classes in society and opting for communism instead, it's not really an argument. There will always be varying levels of privilege and entitlement. Plenty of lords and ladies who inherited it all at birth, and they're not part of the royal establishment.
I don't see royals as better than us. I can't remember which royal was talking about it, but they said that they are "servants of the people" which is an interesting way to look at it.
If there was no monarchy, who would hold the government accountable? Another elected official? Because that's not turning out so well....
I think it's reasonable to give Charles and William a go at being more relevant and modern. Charles can read the room and has spoken regularly of "slimming down" the monarchy. If Charles and William don't make a meaningful contribution then it wouldn't be unreasonable to reconsider the constitution at that point. Elizabeth has been on the throne for so many years but I think fresh ideas and change is what our monarchy needs right now. Sorry Liz.
