The Professional Jockeys Association rejected claims of a "rancid" weighing-room culture after Robbie Dunne was suspended for 18 months following a British Horseracing Authority disciplinary panel hearing into allegations he bullied and harassed Bryony Frost.

An independent panel on Thursday found Dunne in breach on all four counts of conduct prejudicial to horseracing and as a result his licence will be suspended with immediate effect, with three months of the ban suspended. He has seven days to lodge an appeal.

The remark about a "rancid" culture in the weighing room was made in closing submissions to the panel on Wednesday by Louis Weston, representing the BHA.

The PJA had previously appealed for the case to be terminated after elements of a preliminary report were leaked to the press, but the head of the panel, Brian Barker QC, dismissed the notion that this could be perceived as a mitigating factor.

The PJA statement read: "Before the PJA responds to the disciplinary panel's findings, we want to make it clear that the PJA has great sympathy with Bryony Frost and takes no issue with the fact that a complaint was taken to the BHA.

"Bryony felt bullied, it certainly took courage to go through the process she has and we do not doubt the isolation she has felt. The PJA entirely accepts that Robbie Dunne’s conduct as found by the disciplinary panel fell well short of the standard the PJA expects.

"All that said, the PJA does not accept the disciplinary panel’s findings in relation to the culture within and collective behaviour of the jump jockeys’ weighing room. It is a grossly inaccurate and wholly unfair representation of the weighing room and a conclusion we believe is at odds with the evidence presented.

"The PJA does not condone bullying or the use of the type of language the disciplinary panel has concluded was used. Bullying and the use of such entirely inappropriate language cannot and will not be tolerated.

"Whilst we reject the wholesale criticism of the culture within the weighing room, everything is not perfect. There are lessons to be learnt for the PJA and its members and we recognise change is needed. This starts with creating facilities that do not require female jockeys to be in the male jockeys’ changing room in order to do their job, but doesn’t stop there."

The PJA also issued a statement on behalf of a number of female jockeys, which it said wished to remain nameless "having seen the reaction towards anyone who has expressed such views".

Barry Geraghty said it was a "sad" day for racing after the verdict was announced.

Geraghty, winner of the Cheltenham Gold Cup and Grand National in his glittering career in the saddle, aired his sympathy for Frost but stressed that he does not believe the weighing-room culture is as bad as portrayed during Dunne's hearing.

"My reaction is sad I suppose," he said. "There is no winner. Obviously it's tough for Bryony, tough for Robbie and tough for racing as well.

"You’d have to be in the enquiry itself to have a grasp of all the detail, but for me it’s not a reflection on the weighing room and the culture, that’s the bit that really gets me."

Responding to claims from the British Horseracing Authority's Louis Weston, who in his closing statement on Wednesday claimed that the culture in the weighing room was "rancid", Geraghty said: "Not the weighing room I was in for 24 years and I’ve only been gone just over 18 months.

"There is nothing more precious to me than my children and if they decided to pursue a career as jockeys the racecourse would be the only place I would fear for them, not the weighing-room culture, fellow riders or valets.

"The weighing room I was in for 24 years was a happy place, it was good fun. We’d have clashes and differences of opinion, but I never witnessed bullying and if someone was getting a hard time from someone else, someone would generally step in and address the situation.

"It’s hard to hear these comments like 'rancid’ because that is not the place I spent most of my life.

"I’d be all for new measures - if they are brought in - to stop this sort of thing happening again. You don’t want to see an incident like this again. If there is an issue people need to be able to address it.

"But I think it’s unfair to the people in the weighing room to be painted in this way."

"This is 40 years too late" - Gay Kelleway

Gay Kelleway - the first woman to ride a winner at Royal Ascot and now a successful trainer - welcomed the ruling.

Newmarket-based Kelleway told Sky Sports Racing: "This is 40 years too late, this is what I had to suffer back in the day when I was riding and it has taken quite a few decades for a clearer vision of what lady jockeys go through.

"This is not just Bryony, a lot of lady jockeys kept schtum about a lot of things. I know one particular Flat jockey told me about her experiences, but she was too scared to say anything. At last they've heard Bryony and I’m delighted with the verdict.

"I think she can move on from this - look at her, the proof of the pudding is in the eating, going through all this she won the Tingle Creek and she won today, that’s how she does the talking. She’s carried on like a professional, but thank God she had the courage to speak up."

The culture of the weighing room came under intense security throughout the hearing.

Kelleway said: "In my day I wasn’t allowed to put my toe in the changing room, they made it very clear women jockeys were not allowed in so we had our small room to change in.

"Obviously there’s a lot more women riders now, but you don’t see Serena Williams going into Andy Murray’s changing room and racecourses needed this kick up the backside to improve facilities - and why on earth haven’t we got female valets?

"The saying of what goes on in the weighing room stays in the weighing room is a pile of you know what as far as I’m concerned. Everything needs to be more transparent.

"A young jockey should be able to go and complain if they are being bullied or feel intimidated."

Alain Cawley, however, believes his weighing-room colleague has been "hard done by".

Speaking after riding at winner at Newcastle on Thursday, he told Sky Sports Racing: "I think Robbie has been hard done by, (being) found guilty of everything he has.

"I’ve been in the weighing room a long time and I’ve never heard anyone say (anything) but how good it was in there (for all the) young people coming along.

"Going back when all the older boys were there, especially when I was starting - it helped me out.

"For me the weighing room is a great place to be. I haven’t heard many people say that it wasn’t.

"I feel sorry for Robbie. Hopefully it’ll get looked into again - I don’t think it’s right.

"We’re all adults, or the majority of us are adults. We’ve all had tussles and bustles about people - how many married people go home and swear at each other and have rows every night of the week?

"Swearing is part of life and it’s a tough sport we’re in. We risk our lives when we go out there.

"Foul language is used everywhere. I’m not saying it’s right to use it in certain ways, but we’re grown people - men and women in there. We’re tough people to be out there in that game.

"It’s a tough sport, but it’s for everyone - whoever wants to come into the game, we’re open to everyone coming into the game."
