Last year's winner Profitable came home well, but Lady Aurelia extended her advantage in the final 100 yards and passed the post three lengths in front. Marsha, the 11-4 favourite, was third.
Meanwhile, Michelle Payne believes Kaspersky can cause a stir in the Emirates Stakes at Flemington in November after his excellent fifth-place finish in the group one Queen Anne Stakes at Royal Ascot.
The Melbourne-Cup wining jockey gave the six-year-old colt a stellar ride in a hotly contested 1600m opener at the five-day meeting, hitting the line strongly behind odds-on favourite Ribchester, who set a new track record.
Another steaming hot day in the London area ensured a fast-paced track on the straight mile course and after a slow start out of the gate, Payne had Kaspersky in the frame for a place coming into the home straight.
However, she wasn't able to coax him past Mutakayyef, Deauville and Spectre, who finished in the minor places. Payne believes her mount, trained by British-based Australian handler Jane Chapple-Hyam can make a splash in Melbourne, which is where he'll head later this year.
"If he comes over for the old Emirates Stakes he's going to be a real live chance."
