'More people are in Constitution's camp - but there's a pep in Jonbon's step'

Nicky Henderson, a four-time winner of the Supreme, is back in a familiar position this season with two strong chances in Constitution Hill and Jonbon, bringing back memories of six years ago when Altior and Buveur D'Air lined up in the festival opener and finished first and third.

It would be no surprise if Tuesday's duo also ended up in the Seven Barrows Hall of Fame as well, but who wins?

"I think the yard was stronger about Altior than Buveur, but the staff would be pretty split with these," says Charlie Morlock, Henderson's aide-de-camp.
