As Chairman of the BBC Trust, Patten joined the Prince of Wales and other members of the royal family in the royal box for the Queen's Diamond Jubilee Concert. It came, however, immediately in the wake of widespread criticism of the BBC's live outside-broadcast coverage of the Queen's Diamond Jubilee River Pageant on 3 June 2012, which was castigated in the press and was the subject of 1,830 formal complaints by viewers. Patten said afterwards the Royal Pageant had not been the BBC's "finest hour" and admitted that "The tone was wrong."
