He has won three times, having accounted for Mujood over a mile at Goodwood in May, and remains unexposed.

RA Junior, trained by Brian Meehan, is one of only two three-year-olds in the event.
This lightly-raced colt, who showed good form over a mile last season, has solid each-way claims, along with the Brian Ellison-trained Ladies Best, who was a narrow fourth to Duncan on his penultimate start at Epsom.
Howard Johnson won the Norfolk Stakes in 2005 and 2007, so it was interesting that he was represented by KINGDOM OF LIGHT (2.05) in the Group 2 contest at Royal Ascot this year.

FRISTON FOREST (3.45) was very game in defeat behind Som Tala at Doncaster last time on his first try at two miles and this drop back to a mile and three-quarters should be a benefit. He also seems to act on any ground.
