The trophy presenters – usually members of the Royal family or celebrities plus a couple of racecourse sponsors – are organised well in advance for each race.
Sheikh Mohammed and Princess Haya did present the prize for the Coronation Stakes – being the most prestitgious race of the day – to Mrs Jackie Bolger (in whose name she runs) and Mrs June Judd.
That is why Richard Dunwoody was in the rather strange position of having to make the trophy presentation for the Chesham Stakes to The Queen.
