Banbridge overhauled long-time leader Il Est Francais at the last fence to claim a dramatic win in the King George VI Chase at Kempton.
Il Est Francais had been ahead under James Reveley for almost all of the three-mile Boxing Day showpiece and built up a comfortable lead, and with two to go Banbridge was the only horse who looked likely to challenge.
At the last, the leader was less than fluid and the 7-1 chance jumped it better and raced clear for Paul Townend and trainer Joseph O’Brien.
Earlier, the 2023 champion hurdler Constitution Hill made a welcome return to action with a third win in the Christmas Hurdle.
