Sheikh Mohammed's breeding operation Darley has secured naming rights to the four-leg Princess Series for fillies at Randwick.

As part of a new partnership with Australian Turf Club, Darley will offer the breeder of the winner from each of the four races a free service to some of its leading stallions.

The series consists of four races over August and September - the Silver Shadow Stakes, Furious Stakes and Tea Rose Stakes at Group Two level and culminates in the Group One Flight Stakes on September 29.

The winning breeder from the individual races will receive a free 2018 or 2019 nomination to Darley stallions Ribchester (Silver Shadow), Frosted (Furious, Exosphere (Tea Rose) and Astern (Flight).

As an added incentive, the winning filly of the series will also earn a free nomination to any stallion on the Darley roster in the year she retires from racing, or in her first two years at stud if she is by a Darley stallion.

"The Darley Princess Series is a fantastic addition to the racing calendar and we are proud to support the ATC's spring carnival," Godolphin's managing director in Australia, Vin Cox said.

'We are proud of Darley's reputation for looking after our breeders with tangible rewards and this is something we wish to continue to build on.

"The Darley Princess Series at Royal Randwick celebrates the best three-year-old speed fillies in the land and we are proud to reward their owners and breeders with nominations to our world-class Darley stallions.''
