Silk Sari and Albasharah have been supplemented for Saturday's Qipco British Champions Fillies & Mares Stakes at Ascot.
The Luca Cumani-trained Silk Sari staked her claim when winning the Park Hill Stakes at Doncaster, while the Saeed bin Suroor-trained Albasharah was also added to the field at a cost of £35,000 after she was victorious in a Listed event at Newmarket last week.
Last year's winner Seal Of Approval is the mix again for James Fanshawe, although she could finish only fourth behind Silk Sari at Doncaster last time.
Chicquita, last year's Irish Oaks winner, is one of two possibles for Aidan O'Brien, who could also saddle Beyond Brilliance.
John Murphy's Euphrasia, Vote Often from Dermot Weld's yard and the Johnny Murtagh-trained We'll Go Walking are the other Irish-trained representatives.
Pollyanna could be an interesting French contender for John Hammond, with the 13-strong field completed by another Godolphin horse in Tasaday, Cubanita, Hadaatha and Madame Chiang.
