Gay Kelleway won at Royal Ascot on Sprowston Boy in the Queen Alexandra Stakes over 32 years ago.
And while Lizzie Kelly, Bryony Frost and Rachael Blackmore all rode winners at Cheltenham in March have no runs to their name in the grand event.
Even Hayley Turner, twice a Group One winner and the most successful British female rider with more than 800 winners to her name, has missed out at Royal Ascot, although she did finish a head behind the winner on Margot Did in the Albany Stakes in 2010.
In all, 115 runners at Royal Ascot since 1989 have been ridden by women. Female riders are not riding winners at the meeting because, for the most part, they do not get realistic opportunities to do so.
