The last three winners of the William Hill Grand National Trial – Yala Enki, Vieux Lion Rouge and Bishops Road – are among a field of 16 declared for the three-and-a-half-mile handicap chase at Haydock on Saturday.

Last year’s hero Yala Enki, trained by Venetia Williams, tops the weights on 11st 12lb, having carried 10st 11lb when successful by 54 lengths in attritional conditions.
