Fergal O’Brien’s Long Walk winner Crambo, the Gordon Elliott-trained Teahupoo and the enigmatic duo of Asterion Forlonge and Champ have also been declared for what appears a fascinating renewal of the three-mile contest.

The Cheveley Park Stud-owned 10-year-old has not run since November but has a habit of reserving his best for the Festival.

Paul Nicholls’ Stage Star needs to bounce back from a poor run on New Year’s Day but previously won the Paddy Power Chase under top weight. Stablemate Hitman also runs.

Dan Skelton’s Protektorat drops back in trip having had a crack at the Gold Cup for the last two years, Elliott runs Conflated and Fil Dor while Willie Mullins is represented by Capodanno.

The one horse who will not be suited by Tuesday’s rain is Joseph O’Brien’s Banbridge, who was a non-runner at the Festival last year when the ground went soft.

Ahoy Senor, Fugitif and the supplemented Ga Law make up the field.

The third Grade One on the card is the Turners Novices’ Chase in which an open field of 11 has been declared.

There are 21 in the Trustatrader Plate, in which Jonjo O’Neill’s Crebilly is well fancied while Angels Dawn will bid for back-to-back wins in the Fulke Walwyn Kim Muir Challenge Cup Amateur Jockeys’ Handicap Chase
