FRANKIE DETTORI'S Vodafone Derby demons were exorcised in the Epsom sunshine yesterday afternoon as Authorized powered to a stunning success in the premier Classic. Peter ChappleHyam's brilliant colt had far too much pace and class for runner-up Eagle Mountain.

Aqaleem was third, with Lucarno fourth.

Roared on by the huge crowd on the Surrey Downs, Authorized emerged victorious to give Dettori a first Derby triumph in 15 attempts.

Sent off the 5-4 market leader, the three-year-old's success was undoubtedly one of the most popular victories in recent Derby history and cost the bookies an estimated 80 million. Dettori's mount had shown he was a genuine contender for top honours on his seasonal reappearance in the Dante Stakes at York and this performance was even more emphatic.

Sitting well off the early pace set by Kid Mambo, the son of Montjeu was ridden patiently in the early exchanges. Indeed, Authorized was 10th of the 17 runners as the field approached the descent to Tattenham Corner. Dettori's partner travelled like a dream, however, and cruised up to fifth two furlongs from home. A few gentle reminders from his jockey put the race to bed as Authorized skipped away to a five-length verdict from Eagle Mountain. Aqaleem finished two and a half lengths further away.

Although most of the plaudits will go to Dettori, fulsome praise must be afforded to Chapple-Hyam, who has now won two Derbys following Dr Devious in 1992. Having returned to the winner's enclosure with his trademark flying dismount, Dettori said:

"I've been under some pressure but not as much as this.

He has a tremendous turn of foot . . . he's a wonderful horse.

I heard the whole world shouting in the last few yards and it was very emotional. I had to pinch myself at the line to make sure it wasn't a dream, " he said following victory.

Chapple-Hyam said: "He's a very good horse. I've always thought he was from day one.

He's never let me down and has a serious turn of foot. He travels and you can do most things with him. Frankie was probably a bit further back than I wanted him to be but he [Authorized] has got so much class. It's not about me, it's about the horse and everyone at home . . . this is their day."

Authorized's joint-owner Saleh Al Homaizi added: "We just hoped for some luck and it has happened. I always wanted to win this race." Fellow owner Imad Al Sagar reserved special praise for Dettori and said: "The dream has come true and he [Dettori] did a fine job. Peter has also done great a job with the preparation and brought him here perfectly."

Aidan O'Brien, who saddled eight runners in the race, was delighted with the performance of the Johnny Murtagh-ridden Eagle Mountain, sent off at odds of 6-1. The Ballydoyle handler said: "He ran a blinder and if everything's well, he'll hopefully go for the Irish Derby."

Marcus Tregoning was equally happy with Aqaleem.

The trainer, who won the Derby 12 months ago with Sir Percy, said: "It was absolutely brilliant. It was always going to be difficult from his draw and Richard [Hills] gave him a super ride. It was always the plan to ride him that way, although he used up a lot of speed. He's a horse who'll improve through the year."

John Gosden was also proud of Lucarno, who was ridden by Steve Drowne, but admitted his charge had been defeated by a special horse.

Gosden said: "I'm delighted with him. It was only the fourth race of his life after all.

He was a little bit green but the winner was exceptional."

Drowne added: "Nothing was a match for the winner but as the year goes on maybe mine might emerge secondbest. He's picked up and gone by the pace horse and ran all the way to the line."

Elsewhere Stuart Williams and Saleem Golam celebrated the biggest success of their careers as Hogmaneigh weaved himself artfully through the field to take the Vodafone "Dash" Stakes at Epsom. There is only one way to ride this improving fouryear-old, who must be produced with as late a run as possible.

Former joint-champion apprentice Golam did not take an easy route but after swerving past a couple of his rivals, Hogmaneigh (7-1) burst in front inside the distance to take the �75,000 sprint by a neck and a short head from Moorhouse Lad and Caribbean Coral respectively.

"He has got a lot of speed and I am glad he's won a big one as he's a good horse and he deserves it, " said Newmarket-based Williams. "The stable has not been in great form but I was hopeful as he had a good draw and Saleem has won on him before."

The Dash was landed last year by subsequent Prix de l'Abbaye hero Desert Lord and Williams added: "He's in the Wokingham but has other options and is entered in a big handicap in Ireland later this year. I hope he ends up where the winner did last year." Hogmaneigh is a general 10-1 shot for the Wokingham Handicap at Royal Ascot.

Dual-purpose maestro John Quinn struck again on the big occasion as the redoubtable Blythe Knight (4-1) held off 4-5 favourite Blue Ksar in the Group Three Vodafone Diomed Stakes. The seven-year-old is equally capable over hurdles as on the flat and when Graham Gibbons' mount led over a furlong out, he was always going to take some passing.

While Blue Ksar looked a real danger, he could not peg Blythe Knight back and surrendered by a length. Paddy Power introduced Blythe Knight at 33-1 for the 2007 Smurfit Kappa Champion Hurdle, with Coral and Betfred going 16s. He is set now for a break ahead of an autumn campaign.

Peter Chapple-Hyam and Frankie Dettori were in fact opponents in the Vodafone Woodcote Stakes long before their heroic Derby success, with the trainer just coming out on top by a length.

Chapple-Hyam's Declaration Of War (9-2) came with a supersonic late drive to deprive Dettori and Bespoke Boy, who took charge after Baytown Blaze veered wide turning Tattenham Corner.

However, Declaration Of War picked up sharply when asked and took control in the final half a furlong to get home in the lead.
