Hayley Turner became only the second female jockey - and first since Gay Kelleway 32 years ago - to ride a Royal Ascot winner.
Turner got Charlie Fellowes' 33-1 shot Thanks Be home in front by a neck from the Queen's Magnetic Charm in the Sandringham Stakes.
Reflecting on her success, Turner said: "The girls' changing rooms are full now - and it was only a matter of time.
"Gay Kelleway was obviously the first, and great respect to her."
