Johnny Murtagh celebrated his first winner as a trainer at Royal Ascot when Create Belief turned the Sandringham Stakes into a rout.

Murtagh enjoyed many memorable days in the saddle at the meeting – but very few will have given him as much satisfaction as this victory.

Well-backed when the torrential rain hit overnight, Create Belief was sent off a 6-1 chance in a field that saw nine non-runners due to the worsening conditions.

Ridden by Ben Coen – another to be celebrating a first Royal Ascot winner – Create Belief put the race to bed a long way out.

She cruised into the lead with a furlong and a half to run and despite being put up 10lb for a win in a big handicap at the Curragh last time out, she sprinted clear.

Michael Stoute's 5-1 favourite Samoot was the only filly to give any sort of chase, but she had no answer and was beaten five and a half lengths. Messidor was third, with She Do fourth.

Coen sported the colours of the RacehorseClub, who were second in the Grand National with Balko Des Flos.

The rider said: "It’s a huge win and a great feeling to be part of it. She travelled so easily and loved the ground. You can ride her any way you want, she’s such an uncomplicated filly.

"I couldn’t ask for a better mentor than Johnny. It’s my first time here and it’s a big help having someone like him behind me."

Murtagh was delighted to secure his inaugural winner at the showpiece fixture and said: "It feels extremely special. It’s a dream come true. I’m very proud of my family and team. It’s much tougher this training game as you are with them all the time. But the staff have put in so much hard work.

"Royal Ascot is the best week of the year, it’s very special, it’s magical and to come back and train a winner now after all those successes as a jockey, I’m just absolutely thrilled.

"It was not ideal for my filly with an 8lb penalty, but when the rain came it really helped her chances.

"She’s progressing and hopefully she can keep going now. She’s on the up and hopefully she can go on now and be competitive in Group races.

"We always thought she was a stakes filly in the making and she has been working well, so it wasn’t a surprise, maybe how easy she won, but I wasn’t surprised she won today."

Oisin Murphy secured his second win of the day, and his fourth at the meeting, as 7-2 favourite Quickthorn relished the conditions in the Duke of Edinburgh Stakes.

Murphy settled on the heels of the pacesetting Zabeel Champion and was perfectly placed to make his challenge as the field turned for home.

Hollie Doyle shot up the inside rail on last year’s victor Scarlet Dragon, while Raymond Tusk and Mirann tried to take a hand in the finish, but Murphy had plenty up his sleeve on the Hughie Morrison-trained Quickthorn, who stretched clear in the final furlong.

Raymond Tusk was a length and a half back in second, with the gutsy Zabeel Champion beaten three-quarters of a length in third.

Clifford Lee rode his first Royal Ascot winner as the Karl Burke-trained Significantly just held on in the closing Palace of Holyroodhouse Stakes.

Sent off a 10-1 shot, Significantly had posted an eyecatching piece of form last time in finishing second to Dragon Symbol, who was first past the post in the Commonwealth Cup before being demoted to second earlier in the afternoon.

Lee set sail for home with a couple of furlongs to run on Significantly and although he tired at the finish in the heavy ground, he fended off the late burst of Boomshalaa.

Tom Marquand on board Alenquer celebrates after winning the King Edward VII Stakes

Alenquer backed up the form of his Sandown win with a stylish success in the King Edward VII Stakes.

William Haggas' colt won the bet365 Classic Trial at the Esher track with subsequent Derby winner Adayer back in second, and connections had been considering supplementing him for Epsom or going for the German Derby.

However, a setback meant those thoughts were short lived and now they may be wondering what might have been.

Sent off the 13-8 favourite, Tom Marquand was happy to watch the race develop from his position at the rear of the small field as Bellocio and Tasman Bay forced the pace.

Given the testing conditions the race known colloquially as the 'Ascot Derby' could have turned into a war of attrition - but Alenquer moved smoothly up to challenge before quickening up smartly.

Being by German sire Adlerflug the ground was never going to be an issue and he pulled away nicely to win by a length and a half, with Tasman Bay running a cracker in second for former Olympic eventer Sir Mark Todd.

Sandrine maintained her unbeaten record in the Albany Stakes to provide Andrew Balding with his second two-year-old winner of the week.

In very contrasting conditions to the first three days of the meeting, the ground had turned extremely testing and the fixture had to survive a lengthy inspection before being given the go-ahead.

Running in the famous Kirsten Rausing colours, Sandrine is by the American sire Bobby's Kitten so it was a surprise how well she handled the deep ground.

A winner on the all-weather on her debut, Sandrine was sent off a 16-1 chance but she stayed on powerfully under David Probert.

The majority of the field stayed down the middle of the track with only Oscula and Hellomydarlin staying on the rail, and with a furlong to run Oscula - who was third to the winner first time out - still held every chance.

But Sandrine took up the running from Hello You inside the final furlong to come away and win by a length and a half, with Oscula back in third.

Probert said: "She was super fit and hardy for an inexperienced filly, and quite relaxed in the early stages which helped her for the finish.

"We had such a deluge, the ground is loose and they are galloping through it."

Balding won the Coventry Stakes on Tuesday with Berkshire Shadow.
