Alain de Royer-Dupre raided another big prize on the Knavesmire when Dalkala showed her class in the Betfred Middleton Stakes at York.
After winning the Yorkshire Oaks with Shareta last summer, the French handler has good memories of his trips to northern England and Dalkala never looked in any serious danger.
The 2-1 favourite travelled sweetly in the hands of Christophe Lemaire and her Group One form was to eventually prove head and shoulders above her rivals.
Roger Varian's Ambivalent made her work throughout the last furlong but never looked like getting there and was a length behind, with Richard Fahey's Ladys First third and Starscope fourth.
Lemaire said: "She stays very well and stays the trip so I took the lead a little bit early.
"After that she managed to keep the rhythm. She deserved to be favourite today and she won well. We are very happy.
"She is a very easy ride."
