Magical and Addeybb, the first two home in last year's Qipco Champion Stakes, will face off again at Ascot on Saturday with 11 runners declared for this season's renewal.

Aidan O'Brien's durable mare Magical is a seven-time Group 1 winner, adding the Pretty Polly Stakes, Tattersalls Gold Cup, and Irish Champion Stakes to her tally this term after connections rethought retirement plans initially announced at the end of last year.
