‘Oh God, not more Diana.’ We’ve all heard it this summer and Di-fatigue is unlikely to be reversed by the official programme of remembrance. The Wembley concert was truly moving in parts, especially the video inserts which recalled Diana at her spontaneous, compassionate best. I’ll admit they reduced me to tears, and not just because here and there I caught glimpses in the background of a younger, slimmer, more idealistic me.Tears may also be shed in the relatively modest surroundings of the Guards Chapel when on Friday 31 August the Princess is remembered by a carefully vetted congregation. Another cocktail of sentiment, though probably of a brand more acceptable to royal traditionalists.But neither of these events, for all their good intentions, is likely to change perceptions of the late Princess.
