Professor Tim Morris, Director of Equine Science and Welfare for the British Horseracing Authority (BHA), said:

“We are very sad about the fatal injuries suffered by Synchronised and According to Pete in the Grand National.

“In both cases the horse incurred a fracture to the leg and the humane option was to put the injured horses down.

“The Grand National undoubtedly represents a challenge to both horse and rider. It has inherent risks, but, working closely with Aintree and other stakeholders, we do all we can to minimise these risks while maintaining the unique character of the race. We will examine closely the circumstances which led to both incidents.

“The key data from these accidents will be collated, as is the BHA’s policy in the event of any serious equine injury. Each year the BHA and Aintree review all incidents which occur during the Grand National meeting and consider what measures can be taken to address the risk of a repeat in the future.

“The BHA takes its responsibility of looking after the welfare of horse and rider very seriously. We consult and work with recognised welfare organisations such as the RSPCA, SSPCA and World Horse Welfare. It is our stated objective to continue to reduce the number of injuries and fatalities which occur in racing.”
