Councillor Les Sibley, Chairman of Oxfordshire County Council, said: “On behalf of Oxfordshire County Council, it is with great sadness that today we hear of the death of His Royal Highness The Duke of Edinburgh. This sadness, I am sure, is shared by many of you who will want to remember and recognise the service of Prince Philip.
