mister dunn had already admitted one breach of the rules by behaving in a violent or improper manner towards briney frost on that day, but denies similar charges at stratford in 2020 and denies bullying and harassing briney frost over a seven month last year. he says they are benign for cutting across otherjockeys dangerously during races and this is a view shared by other senior jockeys. during his evidence, he also accused the farm amateurjockey of making up some of her evidence about being verbally abused by him. he also denied bullying briney frost around the virtual grand national last year. seven current or former jockeys including the four time champion, richard johnson, who retired earlier this year gave evidence in support of robbie dunn and one of those described him as a class clown who had mocked briney frost.
