John and Thady Gosden’s promising Regal Jubilee makes her seasonal reappearance on Saturday in what promises to be an informative running of the Dubai Duty Free Stakes at Newbury.

The three-year-old is by Frankel out of the mare Regal Realm, making her a half-sister to Sir Michael Stoute’s multiple Group-race winner Regal Reality.

The Cheveley Park Stud-owned bay made her debut at Newmarket in September, but ran no race when hampered in a one-mile fillies’ novice – a performance she put firmly behind her in October when running away with a Windsor novice to prevail by seven lengths.

She then stepped up to Listed level back at Newmarket in the Montrose Fillies’ Stakes, where she shone again in winning by two lengths on heavy ground.

Now returning to action at Newbury, Regal Jubilee will make another step up as she tries her hand on soft ground at Group Three level, in the seven-furlong feature registered as the Fred Darling.

“The stiffer seven at Newbury will suit her, the ground will certainly suit her from what we saw last autumn,” said Cheveley Park’s Chris Richardson.

“I think the trip is the minimum, really, she’s probably bred to be more of a mile-and-a-quarter filly. But it makes sense to go for a trial and see where we go after that.

“Her action favours the more rain-softened conditions we think, but we haven’t got much to go on.

“We’ll take advantage of the slightly easier ground now and see what happens.”

Marco Botti has a fascinating contender in Folgaria, a Due Diligence filly who makes her British debut after joining Botti’s yard from the Italian stable of his brother, Stefano.

She was unbeaten in five starts for Botti’s brother, working her way through Listed, Group Three and Group Two level when taking contests such as the Premio Primi Passi by six lengths and the Premio Dormello by two and a quarter.

Botti said: “She’s unbeaten in Italy, she won over six (furlongs), seven and a mile.

“She joined us about two and a half months ago, the owner decided to see what she can do abroad and it seems a good race to start her off in.

“The ground won’t be an issue, she’s been in good form and her work at home has been pleasing us.

“Of course it’s hard to transfer that form in Italy to England, but it seems the right race to start her off in and see where we are.

“She’s in the French Guineas and this will tell us a bit more about how to compare what she did in Italy to here.

“She won the Premio Dormello in good style, a Group Two, she’s facing a good field at Newbury though it has cut up a little bit.

“We’ve been happy and we will find out whether she’s up to this level.

“She was trained by my brother and we’ve been in touch, she’s been a straightforward filly since she joined us.”

William Haggas is represented by Relief Rally, a Kodiac filly who proved herself to be high quality when meeting with defeat just once in five runs during her juvenile season.

That defeat was a nose loss in the Queen Mary Stakes at Royal Ascot, after which she went on to win the Super Sprint at Newbury and the Lowther Stakes at York.

She was subsequently sold by Simon Munir and Isaac Souede, fetching 800,000 guineas at Tattersalls and staying in the Haggas yard for new owner Zhang Yuesheng.
