Aidan O'Brien is responsible for four of the eight runners as he bids for a fifth successive victory in the Comer Group International Irish St Leger Trial at the Curragh on Saturday.

The Ballydoyle handler saddled Leading Light to claim this Group Three prize in 2014, since which Order Of St George has racked up a hat-trick.

This year's team is headed by Flag Of Honour and Giuseppe Garibaldi who finished first and second respectively in the Curragh Cup over this course and distance in early July. Southern France runs for the first time since chasing home stablemate Kew Gardens in the Queen’s Vase at Royal Ascot, with Family Tree completing the quartet.

Willie Mullins is triple-handed, with Laws Of Spin Renneti and Thomas Hobson all in contention.

The field is completed by Twilight Payment from Jim Bolger’s yard.
