Jeremy Phipps has resigned as the Jockey Club's director of security after being caught on camera making derogatory comments about the membership of British horse racing's regulatory body.
Sunday's edition of the BBC current affairs programme Panorama entitled 'The Corruption of Racing' featured a secretly recorded conversation between Phipps and predecessor Roger Buffham.
Viewers saw former British Army officer Phipps accuse Jockey Club members of lacking "backbone" before going on to question their intelligence.
In a statement today, Jockey Club senior steward Christopher Spence said: "I accepted Jeremy Phipps' resignation with great regret as in his short time with the Jockey Club, first as acting head of security and then as director of security, he has contributed a great deal.
"I think it is a great pity that incidents relating to the filming of the Panorama programme have culminated in Jeremy's resignation."
Phipps said in his letter to Spence that his role had become "untenable". He had caused "embarrassment, for which I apologise most sincerely".
