The government's Scotland secretary Douglas Alexander has admitted it was a "mistake" to appoint Peter Mandelson and "significant lessons need to be learned" over the vetting process. Speaking to Sophy Ridge on Sky News he said: "Peter Mandelson shouldn't have been appointed as ambassador, the prime minister, never mind myself, accepts that was a mistake. "It is possible that as well as the error in terms of the appointment of Peter Mandelson, there are significant lessons that need to be learned on process. One of those lessons that's already been learned is the need to make sure that this deep vetting is undertaken prior to the appointment and announcement of these ambassadors."
