The deaths came despite modifications to three fences following the deaths of two horses in 2011. The British Horseracing Authority, which said it was reviewing the race, released a statement saying the race's safety record had improved and that it was 'premature' to judge the effectiveness of changes to the course.
How I see it

As one of the crown jewels in the sporting calendar, the Grand National was always going to prompt debate.
The BHA was in a tricky position but struck the right balance in its statement: sympathy, a focus on the facts and highlighting a commitment to safety.
Rather than responding to immediate calls for change from media and animal rights groups, it bought itself time to talk to those involved, confirming a review would take place before it reacted.
Owners, trainers, jockeys and sponsors have all been asked to comment on safety this week, and I expect discussions between the BHA and stakeholders will focus on how changes can be designed to reduce the risk further without jeopardising the appeal of this world-class event.
