Saeed bin Suroor is hoping Winning Story can transfer his recent good work at home to the track and maintain his unbeaten record with victory in the Betfred Derby Trial Stakes at Lingfield on Saturday.
In a race that has so far eluded the Newmarket handler, the once-raced three-year-old will bid to change that statistic by adding the Listed prize, which has been won by the likes of High-Rise, Slip Anchor, Kahyasi and Teenoso en route to glory at Epsom Downs in the Derby.
Although unraced at two, the son of New Approach showed a good attitude when making a winning start to his career in a competitive mile-and-a-quarter maiden at last month's Craven meeting.
Bin Suroor said: "He did a really nice piece of work on Wednesday morning which showed he is well at home. He is in good form and is improving all the time.
"I think the step up in trip will suit him and the ground should be fine. We always thought he was a nice horse and one that would get better with time.
"We will see how he goes in this first before we look at the Derby."
While the Queen is no stranger to seeing her famous silks carried to big-race glory, Newmarket maiden winner Carntop will bid to give the Prince of Wales and Duchess of Cornwall their most high-profile success as owners.
The Dansili colt was added to the Investec Derby field at a cost of £8,000 last month.
Trainer Ralph Beckett said: "I was delighted with his run at Newmarket (last October). He has had a good spring and has been working well. This race was always the plan.
"We will see what happens on Saturday, as that will tell us where we will go next with him."
Having sent out subsequent dual Group Two winner Snow Sky to land the extended one-mile-three-furlong event back in 2014, trainer Sir Michael Stoute will rely on Across The Stars, who carries the colours of 2003 Derby winner Kris Kin.
After finishing second on both his starts as a two-year-old, the son of Sea The Stars made light work of opening his account at the third time of asking when running out an easy winner of an all-weather maiden at the Surrey venue last month.
Bruce Raymond, racing manager to owner Saeed Suhail, said: "It was a messy race last time with just the four runners and I think he needed the run and the experience. I thought it was a good enough start to the season.
"The switch to the turf track on Saturday will definitely help and we are hoping he can go well.
"I am not saying he is going to win, but he has been showing much more in his work and Sir Michael has got a good opinion of him."
The field is completed by the Landofhopeandglory, who is bidding to give trainer Aidan O'Brien a fifth victory in the race, and second in succession having won it with Kilimanjaro 12 months ago, and the Richard Hannon-trained Humphrey Bogart.
