John Gosden's Starboard took top honours in the Prix du Prince d'Orange at Longchamp.
Ridden by Christophe Soumillon, the three-year-old made most of the running and pulled clear in the straight to win by three lengths from Prince Mag with Albion a head away third.
Godolphin's Mandaean never got into contention and could only finish sixth of the runners.
In the Prix des Chenes, British raider Deauville Prince, trained by Tom Dascombe, had to settle for fourth place behind Pearl Flute.
