Bookies' favourite Tiger Roll has won the Grand National at Aintree today.

Looking to emulate Red Rum's double more than 40 years ago, the 7-2 favourite for the historic race is the shortest-priced winner the race has seen since Poethlyn (11-4) 100 years ago.

Many punters were expected to lay down bets on Tiger Roll, as bookmakers estimated £150m were places on the 172nd running of the Grand National.

Jockey Davy Russell rode Tiger Roll this year, as the field of 40 horses headed out at around 5.15pm on Saturday.

Among the other runners and riders in the field included Anibale Fly, Vintage Clouds Rathvinden and Pleasant Company.

Aniable Fly, ridden by B J Geraghty, was priced with some bookmakers at 16-1.

Rathvinden was one of the favourites at around 10-1, but is some way behind the 7-2 odds of Tiger Roll.

Bookmaker Brian Clarke gave ITV News a run-down of the runners and riders for this year's race:

Thousands were expected to flock to Aintree today, just as they did for Ladies Day on Friday.

Police confirmed two arrests at the event yesterday.

Event Commander, Superintendent Louise Harrison said: "I would repeat my advice to race goers that they should arrive in plenty of time to pass through security and not bring large bags or too many items as this can slow the process down."
