Gavin Grant, chief executive of the RSPCA said:
The death of two horses at the Grand National, bringing the total to three at the Aintree meeting, is totally unacceptable.This is the second year running that two horses have died. In it's current format, the risks to horses are not appropriate and we want an urgent examination of the Grand National, including a number of fences including Beecher's Brook where horses are continuing to die despite safety improvements.
It would appear the whip was overused in the final stages of the race. If that is the case it is totally unacceptable and given the narrow margin of the win I believe the result should be reversed.
