The three-year-old colt Delius eclipsed the record for the highest priced lot ever sold at the Tattersalls Autumn Horses in Training Sale when selling for 1.3 million guineas on Tuesday.

Trained by Jean-Claude Rouget for the Coolmore partners, Delius is a son of Frankel who was unraced as a two-year-old and ran six times this year. He won his first three starts, including a Group 3 race, before starting favourite for the Group 1 Grand Prix de Paris, in which he finished third.

Following a summer break Delius finished second in the Prix Niel and then came home eighth of 16 runners in the Prix de l'Arc de Triomphe.

A wildcard entry for this week's sale at Newmarket, Delius duly broke records when sold for 1.3 million guineas to De Burgh Equine, McKeever Bloodstock, Go Bloodstock and trainers Gai Waterhouse and Adrian Bott. It was the highest priced horse ever achieved at the Tattersalls Autumn Horses in Training Sale.

An opening bid of 500,000 guineas set the tone for proceedings with bloodstock agents Alastair Donald and Guy Mulcaster among those involved in the early exchanges, but bidding was eventually narrowed down to an online bidder and the eventual purchasers, with Hubie de Burgh offering the successful bid.

"It is a joint venture," said de Burgh. "It is for Sir Owen Glenn's Go Bloodstock, who has had some good horses including Lady Of Camelot trained by Gai. He wants a Cup horse, and Gai did as well, so this joint venture came together."

Of the three-year-old colt, bred by David and Trish Brown of Furnace Mill Stud and purchased by M.V. Magnier for 675,000 guineas at the Tattersalls December Foal Sale, De Burgh said:

"What can I say about him? He is a son of Frankel, he is Timeform rated 118, he has raced six times, he has won over 10 and 12 furlongs and he has a perfect profile for Australia. His only slight disappointing run was in the Arc when he hated the ground.

"It is a lot of money, but that is what this sort of horse costs. We have been trying to buy this horse for a long time and I had Stevie O'Connor, Sir Owen's racing manager, on the phone and he was quick to come back with the bids. It was going to be hard to buy the horse on our own as it is a lot of money, so by joining up with Gai and us all getting involved it has given us this opportunity."

Four of the top five lots on Tuesday were bought by Australian interests.

Chris Waller bought the Ralph Beckett-trained Hutchence for 460,000gns. Another by Frankel, this three-year-old won three races from nine starts and has a Timeform rating of 107.

Beckett also trained Mr Monaco, a three-year-old by Territories, who was sold for 410,000gns to clients of Australian trainer Ciaron Maher.

Henry Dwyer, who saddled Asfoora to win the King Charles III Stakes at Royal Ascot this summer, will train Atlantic Coast, sold out of Joseph O'Brien's yard for 340,000gns. The three-year-old Kodiac colt won the Group 3 Killavullan Stakes at two and claimed the Listed Prix Matchen on his most recent start.

The only one of the top five lots on Tuesday staying in Britain is Caviar Heights. This son of Sea The Stars was a listed race winner for trainer Karl Burke this year and now moves to William Haggas, having been bought today by Sam Haggas for 520,000gns.

Sam Haggas said: "I hope the horse can develop into an international campaigner, my parents have had a lot of success taking horses to Sydney for the Autumn Carnival and I hope he can develop into that sort of horse, that would be the dream. He has been on my radar since the spring and his first run in the Fielden Stakes behind Jayarebe, with Ambiente Friendly a place behind him.

"Caviar Heights then put in a massive performance when he won the Newmarket Stakes. It was so impressive, especially on the clock. He beat a very good yardstick in Sayedaty Sadaty and beat him well, and that horse went on to hold up the form when running to a similar level in the Derby. The Derby has some very good form lines this year, it looks a strong Derby."

Haggas added: "I am hoping that this horse can get back to that level of form, and if he can, they can have a lot of fun with him."

The sale continues on Wednesday and concludes on Thursday.
