Lady Aurelia and Ribchester's victories may have matched the script on the opening day at Ascot.

It was a thrilling, exciting and hot first day at the Royal meeting, here's to more of the same tomorrow.
See you at 09:00 BST tomorrow morning for some more horsing around.
Quite a day for Godolpin as Sound And Silence, ridden by William Buick for trainer Charlie Appleby, completed a 124-1 treble.

Good luck if you're having a wager in the last at Ascot - the Windsor Castle Stakes looks a very competitive affair.
