Kauto Star became the first horse to claim a record four consecutive victories in the King George VI Chase.
The 8/13 favourite thrilled the huge Kempton crowd and was never challenged once he took the lead on the home turn, winning by more than 30 lengths.
Ruby Walsh safely guided the dual Cheltenham Gold Cup hero over the last three fences for a comfortable win.
The triumph for the nine-year-old Kauto Star sees him eclipse the achievements of Desert Orchid, who won the traditional Christmas showpiece four times in the space of five years from 1986-91.
In what already looks like a two horse race for the Blue Ribbon showpiece in March, Kauto Star looks set to go head to head with Betfred’s 5/2 second favourite Denman once again.
