Richard Hughes has given up his riding licence after receiving a second ban for misuse of the whip in four days at Kempton.
Hughes received a five-day ban for hitting More Than Words too many times inside the final furlong in Kempton's 1920 race on Thursday evening.
He subsequently handed in his race licence in protest.
"I've handed in my licence as of tonight," Hughes told Racing UK.
"I can't ride horses knowing that I'm not doing myself and the owners who pay £100 a time justice," said Hughes. "I will only consider starting again if there is a review of the rules. I'd rather sweep roads than do half a job. I've notified Richard [Hannon]."
"We're allowed to hit them seven times and both times I've been done, I've hit them six times, which is less than the amount you're allowed and I've got a fifteen day ban because of it and I miss the Breeders' Cup.
"They've made the rules so you hit them more, so you have to get two into them before the furlong pole as then you've only got five left. I was always told as a young jockey the last jockey who goes for his whip normally wins."
"They're taking the art of race riding away from me, it's like telling Messi not to use his left foot anymore."
Ta TW for the sig.
