Total whitewash and have to say I am hugely suspect that this poor horse was put down due to worm infestation, more likely for a public relations exercise.
I occasionally acted as groom for my brother when he was competing his pair a couple of year ago.....I remember only too well the well deserved roasting and tongue lashing I got from him when I jumped down from the carriage, and failed to immediately go to the horse's head and take hold of them by the bridle whilst he dismounted from the driver's seat.:redface:
The fact that this horse was kept in harness, but its bridle removed to allow it to eat hay (never mind it was only a 4 year old) just proves the point that the owners/handlers were totally incompetent and should have never been in charge of a driving horse, let alone giving people rides in the cart!:devil:
