Jonbon is the current favourite in the betting odds to win the Clarence House Chase at Ascot on Saturday.

Current Champion Chase favourite Jonbon is odds-on to win the race following victories in the Shloer Chase at Cheltenham and the Tingle Creek prior to Christmas.
However, two-time Festival winner Energumene returned after a 593-day absence to record an impressive win in the Hilly Way Chase at Cork in December.
Time will tell if Tony Bloom's horse can still perform at the top level but an intriguing battle awaits if both Energumene and Jonbon are at the top of their game this weekend.
Edwardstone, who was a faller in the Tingle Creek before finishing second in the Desert Orchid Chase, also lines up for Alan King, while outsider Boothill completes an impressive quartet.
