Lunchtime betting update from Aintree
William Hill are bracing themselves for a potentially massive payout should Seabass land a huge Grand National punt this afternoon.
Seabass has been by far the best backed horse (7-1 from 12-1) in the big race with William Hill, with liabilities set to top £2m.
This has proved to be the busiest betting event of the year with bets flooding in across all our channels - in our 2400 shops, online, via mobile, telebetting and on text.
The others that have been heavily supported with William Hill have been On His Own (10-1 from 12-1), Teaforthree (12-1 from 14-1) and Imperial Commander (14-1 from 18-1).
Such was the sustained ferocity of the gamble on Seabass that we were forced into suspending betting on ‘which horse will start favourite' mid-morning.
William Hill spokesman, Richard Thomas, said, "Seabass is set to start the shortest price favourite since Hedgehunter (6-1) in 2006, and could be the shortest priced winner since L'Escargot (13-2) in 1975. Whilst a victory for the Katie Walsh ridden, Ted Walsh trained Seabass would be a fantastic story for the Grand National, it would be a painful blow for bookmakers."
