Constitution Hill claimed a comfortable win in the Aintree Hurdle on the opening day of the Grand National meeting.
The Champion Hurdle victor, who went off as 2-15 favourite, led from start to finish and was never challenged.
It was a seventh win out of seven under rules for the six-year-old, who is one of the stars of the sport.
Earlier, Shishkin, also trained by Nicky Henderson, swooped late to win the Aintree Bowl.
