AIDAN O’Brien may not have added to his Epsom Derby tally on Saturday, but he only had to wait 24 hours for Derby success as St Mark’s Basilica added the Group 1 Qatar Prix du Jockey Club to his earlier Poulains victory and gave the Ballydoyle operation a first success in the Chantilly race.

It was pretty much smooth sailing for jockey Ioritz Mendizabal and his mount as they were always handily placed from their inside draw before quickening sharply passing the 400-metre marker to leave their rivals toiling.
