Andrew Mountbatten-Windsor has been arrested on suspicion of misconduct in public office by police investigating his dealings with Jeffrey Epstein.

Officers searched the Norfolk property as well as Mountbatten-Windsor's former home in the Royal Lodge in Great Windsor Park. Lucy Hough speaks to the Guardian journalist David Pegg
