Let’s not beat around the bush: the biggest news in the world is the arrest of Andrew, the King’s brother. It’s huge, not least because the last time a royal was arrested was around 350 years ago, when Charles I was taken prisoner and ultimately executed.

What also makes this so significant is that Andrew wasn’t, as is usually the case with celebrities, politely asked to come into a police station to assist with inquiries. He was arrested at his home, which was then searched by police for further evidence. That distinction is massive.

That said, anyone predicting either the collapse or the survival of the royal family today is being premature — and there’s plenty of that going on. The charge Andrew faces, misconduct in public office, is apparently very difficult to prove in the UK because of the way the law is written. So this may end up going nowhere.

So far, I’d say Charles has handled both today’s developments and the wider scandal leading up to them far more decisively than even the late Queen handled Andrew’s previous indiscretions, and that does help the monarchy. Most importantly, the key figures in the royal family — William, Kate and their children — seem far enough removed from anything Andrew may have done to remain safe from fallout.

On the other hand, what’s happened today is only the beginning. Next may come formal charges, then potentially a prosecution, then possibly a judge and jury. If it gets that far, the risk to the royal family increases dramatically, because it could reveal who knew what about Andrew’s behaviour, and for how long.

If you’re looking for a silver lining, it’s this: the system is working. No one is above the law — not even the brother of the King.
