THE focus of the action tomorrow afternoon will be Ascot, where Politologue will go off a warm favourite for the feature Clarence House Chase at 3.35. But with Defi Du Seuil having plenty to prove and Waiting Patiently better fresh, we could be in for a massive surprise. First Flow certainly attracts the eye following his impressive win at the track last time out, but he will surely need to fence better in this higher grade — so I am going to take a chance on FANION D’ESTRUVAL. The Venetia Williams-trained youngster was set to successfully give 3lbs away to the classy Magic Saint at Cheltenham before pecking badly at the last obstacle, but by and large his fencing is sound.
