Christophe Soumillon brought Shamdala with a perfectly-timed run to lift the Group Two Prix Chaudenay at Longchamp.

Christophe Soumillon believes Shamdala, his mount in the Aston Upthorpe Yorkshire Oaks, has the potential to be as good as Irish Oaks winner Shawanda.

Hot favourite Divine Proportions (8-11) maintained her unbeaten record with a stylish success in the Prix Marcel Boussac Royal Barriere Deauville.
