POLITOLOGUE recorded a wide-margin success in the Unibet Desert Orchid Chase at Kempton.
Paul Nicholls’s grey was the 8-15 favourite to add to his triumphs in the Haldon Gold Cup at Exeter and the Tingle Creek at Sandown.
Special Tiara, who was bidding for a third victory in the Grade 2, made a mistake five fences from home, taking off too far away from the obstacle and paying the penalty with a crashing fall.
His exit left Politologue in a clear lead and he safely negotiated the remaining fences to seal a 13-length success.
Vaniteux finished second and Forest Bihan was last of the three finishers.
Winning jockey Sam Twiston-Davies said: “First of all it’s good to see Noel (Fehily) cantering back on Special Tiara.
“That’s always a good thing to see and he’s a legend of a horse.
“This fella has been brilliant. He’s jumped and travelled. He’s not the best in front but at the same time he’s got the job done and he’s very good in these conditions.”
