Former UK ambassador to the US Peter Mandelson has been arrested on suspicion of misconduct in public office. 

Mandelson was fired and has been under investigation over his alleged ties to Jeffrey Epstein. 

It comes as Australian Prime Minister Anthony Albanese has written to his UK counterpart Keir Starmer, calling for the former Prince Andrew to be removed from the royal line of succession. 

Australia correspondent Donna Demaio told Ryan Bridge the line of succession is a very complex legal framework. 

She says the charges require all Commonwealth countries to pass new laws, but Albanese says they're grave allegations and Australia takes them very seriously.
