A HORRIFIC video has emerged of eventing 'great' Sir Mark Todd of him whipping a horse TEN times with a stick and has sparked fury online.

Responding to the shocking video footage going viral again this week, Sir Mark issued a grovelling apology and said he was 'very disappointed in myself'.

The UK's national governing body, British Equestrian, said they were 'extremely dismayed' by the actions of those appearing in the clip.

In the video, the horse jumps from side to side, but still doesn't move forwards through the water obstacle, and the animal is hit ten times before jumping into the puddle, the footage shows. People can then be heard cheering as the horse trots through the pool of water.

Meanwhile, equine and farm supply company Equiwarehouse shared the video to its Facebook page and said it would no longer be selling any Mark Todd products in response.

The company wrote: 'With no regret at all, we will no longer be selling any Mark Todd clothing, horse wear or feed.

'Mark Todd Eventing you should be utterly ashamed of yourself, vile 'professional' and disgrace of a human.'

This disgraceful scene of animal abuse is NOT something expected of a person awarded with honors for service to equestrians.
