Move Swiftly gave trainer William Haggas his second winner of the week, and his 10th overall, when taking the G2 £175,000 Duke of Cambridge Stakes under Danny Tudhope - who was scoring at Royal Ascot for the third time in two days.

The 9/1 chance, a daughter of Farhh, beat Rawdaa (Sir Michael Stoute/Frankie Dettori) by a neck.
Haggas's first winner of the meeting was Addeybb, who won Tuesday's Listed Wolferton Stakes under Tudhope.
Haggas said: "I'm thrilled to bits with this filly and she enjoyed the ground. We took a few to Newbury to work and she worked nicely. She's run well. The other one, Pretty Baby, didn't go on the ground and probably didn't get the trip either.
"I haven't got any plans for her. She's won here!
"I'm very proud of what everyone [in his team at home] has done. She's been hard work, but she's very tough and very genuine. She went off to be covered and, fortunately, didn't take to New Approach, so she came back and this is the result. We're absolutely thrilled to bits.
"As for the trainer making the decision to run his star filly [Sea Of Class, fifth on her seasonal debut in the G1 Prince of Wales's Stakes] on this horrible ground, it's something I have to take responsibility for. I was very disappointed with myself, but I was extremely grateful to the jockey [James Doyle] for giving her as kind a race as possible and I'm sure she'll bounce back."

Danny Tudhope went to the top of the QIPCO Royal Ascot Leading Jockey award standings after he registered his third victory of the week at the Berkshire venue following the success of Move Swiftly.
Tudhope, registering his fifth victory overall at the Royal Meeting, was successful yesterday aboard Lord Glitters in the G1 Queen Anne Stakes and Addeybb, also trained by Haggas, in the Listed Wolferton Handicap.
He said: "Move Swiftly did it well. I didn't want to be too far back but I ended up being there for some reason. She travelled nicely and enjoyed the ground. I think she will improve for that run again.
"I think they have always liked her and she has been a decent filly. This was her first run this year so she is bound to improve. I felt like she was just getting tired on me and I think there is more to come.
"I couldn't have imagined riding three winners at the start of the week but we are having a great week and I am riding for good people."
Tudhope is riding at Ripon tomorrow, but has rides at Royal Ascot on Friday and Saturday.

Royal Ascot looked set for a Ryan Moore and Frankie Dettori finish to the one-mile G2 Duke Of Cambridge Stakes.
At the two-furlong pole, Moore, riding the Aidan O'Brien-trained I Can Fly (7/2f), was tracking down the outside of the field in the lee of Dettori on the Sir Michael Stoute-trained Rawdaa (4/1). I Can Fly was then asked to quicken alongside, and joined Rawdaa for the lead, but the pair were joined by Move Swiftly (9/1) inside the final furlong.
I Can Fly, who carried a 3lb penalty and was conceding that amount to all her rivals, faded from that point, and while Rawdaa rallied, the William Haggas-trained Move Swiftly scored by a neck. There was a length and three-quarters back to I Can Fly, while Veracious, a stablemate of Rawdaa, was beaten a further length into fourth place.
The second and third hold entries in the G1 Pretty Polly Stakes over 10 furlongs and the G1 Falmouth Stakes over a mile, but they seem unlikely to face each other soon.
Sir Michael favours going back up in trip with Rawdaa, and said: "Both my fillies ran very well, but were beaten fair and square. I think a mile and a quarter is her trip. We have to look at the Falmouth and see what else might be running, but I'm favouring a mile and a quarter."
Dettori's vignette on the race was: "She ran a superb race - the winner was just too strong. I can't fault her, she really tried."
O'Brien said: "She ran very well and I'm delighted with her run. We think she will progress as the year goes on, and we weren't expecting this type of [rain-softened] ground. There's more improvement to come. I should think the Falmouth is a possible for her next."
Ryan Moore, who rode I Can Fly, said: "She ran super but was carrying a penalty. I am very pleased with her."
