As excitement mounts over Prince Harry and Meghan Markle’s wedding, this documentary sees Sir Trevor McDonald and Julie Etchingham talking to those who designed dresses, baked cakes and made bouquets for royal weddings in the past.

Elizabeth Emanuel, who with her then husband David created Princess Diana’s wedding dress, recalls how hard it was to keep the design a secret from the press.

And florist David Longman, whose family have made bouquets for several royal brides, recounts how his father had to hastily make another floral garland for the then Princess Elizabeth after the original one got lost on her big day.
