The former Prince Andrew, brother to King Charles and the rumoured favourite child of Queen Elizabeth II, is now in police custody, accused of misconduct in public office.

It is a stunning fall from grace for the former Duke of York, who was celebrating his 66th birthday today.

He was visited by officers at his new home on the Royal Sandringham Estate.

He's faced numerous allegations over his links to Jeffrey Epstein, but denies any wrongdoing.

I asked our UK Affairs correspondent Rob Watson what he made of it.

Now, there are multiple allegations relating to Mr Mountbatten and Windsor's relationship to Jeffrey Epstein.

He denies wrongdoing, of course.

What should we make of these suspicions of misconduct in public office that have been cited?

Now, the Deputy Prime Minister, David Lammy, says nobody in this country is above the law.

But did you ever think you'd see a senior member of the royal family arrested?

The BBC understands that Buckingham Palace and King Charles were not informed of the arrest in advance.

The King has issued a statement saying he learnt about the news with the deepest concern, adding that the law would now take its course and the royal family would give its full and wholehearted support and cooperation.

I asked our royal correspondent, Johnny Diamond, just what this means for the royal family and King Charles himself.

Talking of the House of Windsor, it's hard to believe this would have happened in the time of Queen Elizabeth II.

Does this raise questions about how she dealt with the scandal?

Now, we were trying to work out when was the last time that a senior royal was arrested.

It seems to have been King Charles I during the English Civil War.

What does this moment mean for the British public?
