St Nicholas Abbey heads a field of six in the Diamond Jubilee Coronation Cup at Epsom on Saturday.

Last year’s victor attempts to become the first dual winner since Warrsan struck for Clive Brittain in 2003 and 2004, as well as trying to give trainer Aidan O'Brien his sixth success in eight years.

The five-year-old gained a one-length verdict over Midday in a five-runner affair for the mile-and-a-half Group One last season and ended 2011 on a high by landing the Breeders' Cup Turf at Churchill Downs.

However, he has been beaten into second place on his two starts this year, most recently being unable to catch his pacemaker Windsor Palace in the Mooresbridge Stakes at the Curragh.

O'Brien took Windsor Palace out of the race at the final declaration stage as well as Treasure Beach but will also be represented by Robin Hood.

Ed Dunlop's Melbourne Cup runner-up Red Cadeaux goes to Epsom on the back of victory in the Yorkshire Cup while William Haggas is hoping for better from Beaten Up, who lost his unbeaten record when sixth in the Dubai Sheema Classic at Meydan in March.

John Gosden's 2011 St Leger winner Masked Marvel and Quest For Peace from the Luca Cumani yard complete the confirmations.

Godolphin's Dubai World Cup hero Monterosso was the only other withdrawal.
