Aidan O'Brien is responsible for 16 of the 29 entries in this year's Ladbrokes St Leger at Doncaster on September 12.

Aloft, Bondi Beach, Giovanni Canaletto, Highland Reel, Order Of St George and the fillies Together Forever and Wedding Vow are among his huge army.

Hugo Palmer has entered impressive Irish Oaks winner Covert Love, while Storm The Stars, placed in two Derbys, is currently 5-1 favourite with the sponsors.

Mr Singh, Balios and Jack Naylor are other possibles to catch the eye.

Mikel Delzangles will make a decision as to whether he sends over Vengeur Masque following his run in the Prix de Reux next month.

Although the French handler feels the unexposed three-year old is a talented individual, he has warned that an outing in the Classic at Doncaster hinges on his performance in the extended mile-and-a-half Group Three contest at Deauville on August 9.

Should Vengeur Masque take his place on Town Moor, he would be Delzangles' first runner in the race.

Delzangles said: "Vengeur Masque is very well. He is going to run in the Prix de Reux at Deauville on August 9 and after that we will decide if he is good enough to go to Doncaster.

"They were nice performances the last two times. The form of the races is OK - the horse he beat won a big handicap subsequently - but definitely not enough to prove that he is good enough to go for the St Leger. He has got to prove himself in a Group race first.

"I do feel he is a quality horse, though, and he is improving all the time. He is very laid back and will love going the extra distance."

Vengeur Masque is one of two French-trained entries left in the Leger, with the other being the Francis Graffard-trained Sumbal.

Having won the Group Two Prix Greffulhe at Saint Cloud back in May, the Qatar Racing-owned three-year old was last sighted finishing fifth in the French Derby behind New Bay.

The scratchings deadline for the St Leger is on August 25, with the six-day confirmation and £50,000 supplementary entry stages following on Monday, September 7.
