Sandy Thomson has lost count of the emails, text messages and letters he has received.
The vast majority sympathise over his stable's devastating loss of Grand National runner Hill Sixteen. But others lambast the trainer, who bid a tearful farewell to his horse at the first fence.
In the face of criticism, Thomson has stood firm, putting the blame at the protestors' door. He says Hill Sixteen, a proven Aintree performer, was stirred by their actions to delay the start of Saturday's race. Thomson, who has two runners in today's Coral Scottish National, feels the activists used Aintree to push their agenda for a plant-based food system.
