Delta Work has emerged as the outright favourite to win the 2023 Grand National at Aintree.
The recent Cheltenham Festival winner and last year's third runs for Gordon Elliott and in the Gigginstown House Stud silks famously carried by back-to-back winner Tiger Roll in recent years.
Delta Work is generally 9-1 and clear at the top of the market with interest in Ain't That A Shame reportedly drying up, as he drifted to 10/1. Corach Rambler, favourite in the build-up to the National, is also a 10/1 chance.
