Trainers from 6 different countries are represented in today's big race at Royal Ascot, the Diamond Jubilee Stakes.

Last year it was won by Australian mare "Black Caviar".

Tom Hogan's "Gordon Lord Byron" will lead the Irish challenge for the Group 1 contest while Eddie Lynam will be hoping for a sprint double as he saddles "Slade Power" after stable mate "Sole Power" won the King's Stand Stakes earlier in the week.

The opening race of the afternoon is the Chesham Stakes at 2:30pm.
