Racegoers who share the names of the soon-to-be wed Royal couple will be granted free admission to the Spring meeting at Epsom Downs racecourse.
Kates, Catherines and Williams will all get to see the race on April 20 for free, in honour of their Royal namesakes Prince William and fiancée Kate Middleton.
Rupert Trevelyan, managing director of Epsom Downs Racecourse, said: “This is a special day for us as we launch the 2011 racing season and build up to the Investec Derby Festival, as the Royal Wedding is for the nation.
“There will be plenty of entertainment for all the family on and off the course and we look forward to welcoming anyone with the Christian names; William, Catherine or Kate for free.”
The Royal wedding will take place on Friday April 29 at Westminster Abbey and will be marked by a public holiday.
