The arrest of Andrew Mountbatten-Windsor tells me several things, one of which is how much the late Queen really dropped the ball on this one. And that’s putting it politely.

She was the one who protected him when all the stories started to emerge. She was the one who, apparently, helped him out with some of the hush money paid out to one of his accusers.

Which only fueled the impression - rightly or wrongly - that the Royal Family thought it was above everything and everyone else.

Which is why I think this development is a brilliant opportunity for the monarchy.

Because this takes the monarchy down a peg or two, which can only be a good thing in the public’s eyes.

King Charles obviously sees an opportunity. He hasn’t been slow in coming forward, saying “the law must take its course”.

We’ve also got the likes of Major General Alastair Bruce, who is a historian and a royal watcher for Sky News, saying that this is “the most shocking day for the British Crown, to have a former prince of the blood arrested”.

Other commentators are describing the arrest as “extraordinary”, “unprecedented”, “spectacular” and a “body blow”.

Whether it is a body blow remains to be seen. Because these developments overnight show that the monarchy is just as answerable as the rest of us. Which is no bad thing, is it?
