A race horse owned by Ryanair chief executive Michael O’Leary won the Grand National for the second year running.

The 4-1 favourite Tiger Roll won its second straight Grand National at Aintree on Saturday with a prize of £561,300.

It was the first horse to do so in 45 years when Red Rum achieved back-to-back wins in 1973-74. Red Rum also went on to win the race again in 1977.

However, O’Leary told Racing TV’s Luck on Sunday programme: “It’s very unlikely that he’ll come back and run in it again next year.

“He will be carrying top-weight, he is a small horse and every time he runs now I get nervous – I’d hate for anything unfortunate to happen to him while he’s racing.

“For his sake and for the sake of the race, I really wouldn’t want to bring him back shouldering huge lumps of weight.

“There’s no reason to emulate Red Rum’s feat. Red Rum saved the Grand National and put it back on the map at a time when it was struggling.”
