Ger Lyons' Endless Drama and the Aidan O'Brien-trained duo of Cougar Mountain and Dick Whittington are the three remaining Irish entries among 17 horses left in the Queen Anne Stakes following the confirmation stage for the mile Group 1 that opens the five-day Royal Ascot meeting on Tuesday.

American mare Tepin is also set to line up. The five-year-old, trained by Mark Casse, has been under consideration for this race since winning the Breeders' Cup Mile at Keeneland last October, despite concerns about her not being able to run with her usual Lasix and nasal strip.

The prolific mare's other possible rivals include Jean-Claude Rouget's Coronation Stakes scorer Ervedya and Lockinge Stakes winner Belardo, trained by Roger Varian.

Others in the mix include Clive Cox's Kodi Bear, André Fabre's Esoterique, Henry Candy's Limato, the Richard Hannon-trained Toormore and David O'Meara's Amazing Maria.

Roger Charlton has kept Time Test in the reckoning, although he is more likely to contest the Prince of Wales's Stakes the following day.
