Last week the former Prince Andrew was arrested, Monday evening it was the turn of Peter Mandelson.
Lord Mandelson has held high office in the Labour Party, the British government, the European Commission and, until last September, the diplomatic service.
He was arrested on suspicion of misconduct in public office and led away from his home into an unmarked car as police searched his properties.
As he helps the police with their inquiries, where does his arrest leave the British establishment?
