The 20-year-old revealed in July that she had retired from the sport after making a formal complaint to British Gymnastics and not because of injury.

Her revelation came as pressure increase on the national governing body, following a series of allegations from gymnasts.

Reports included claims that athletes were forced to practice until their hands bled and were scared to put on weight.

Tinkler later revealed part of her complaint to British Gymnastics in December had "related to my experiences with Amanda Reddin and the national performance coaching set up at British Gymnastics between 2016 to 2019".

The Olympic floor bronze medallist at Rio 2016 has been critical of British Gymnastics handling of her complaint.

Speaking to ITV News, Tinkler criticised Reddin’s treatment of her and other gymnasts.

She alleged that Reddin had often commented on her weight, warning that she was too heavy and she needed to get fitter.

Tinkler said that at a training camp prior to the World Championships, Reddin had addressed the whole team after cleaners had found sweet wrappers in the girls’ bedrooms.

"Amanda came over to us and was like, I can be a bitch when I want to be a bitch and this is one of them times and basically just went psycho at us for having sweet wrappers in our rooms," Tinkler told ITV News.

"There was a girl there who she liked the look of, her body shape was ideal for her and she said, you should all look like this girl.

"But not one gymnast has the same body shape.

"We got told that our bodies are very similar to the Americans and that they look good and they look muscly and we got told that we just look fat."

Tinkler has also blamed Reddin for an ankle injury which forced her to miss the Commonwealth Games in the Gold Coast in 2018.

She alleged Reddin had forced her to train which had led to the injury.

"Not once did she ever take into account how I was feeling or how upset I was with the situation and how I lost my dream of going to a Commonwealth Games," Tinkler said.

"It was always, but you should be doing this by now and it’s been over the timeframe it should have been and you need to lose weight and you're too heavy, you need to get fitter.

"I know your shoulder hurts but bars are the only thing you can do at the minute and that's the only thing that'll get you fit.

"There was never any support at all from Amanda during that point in my career."

Reddin temporarily stood down from her role as British Gymnastics head coach in August.

She stepped aside head national coach to allow an investigation to proceed into claims about her conduct.

British Gymnastics has promised the investigation will be completed by an external independent expert and any outcome actioned immediately.

"In August, I agreed with British Gymnastics to temporarily step aside from my role as Head National Coach to allow an investigation to proceed into claims about my conduct as a coach," Reddin told ITV News.

"The investigation is underway and being completed by an external independent legal expert.

"I am keen for this to conclude and will be fully supportive of the independent investigator by submitting all relevant information and evidence I have in response to these allegations."

"The incidents recounted by Amy are completely unacceptable in our sport," British Gymnastics said.

"Investigations are already underway into a number of these claims.

"These allegations, and any additional information Amy wishes to submit, will be provided to the relevant investigations.

"Any gymnast who feels they have been mistreated can play their role in helping to change the sport for the better by reporting their concerns to our Integrity Unit at [email protected] or, if they would prefer, by calling the BAC/NSPCC Helpline on 0800 056 0566."

An independent review into British Gymnastics is currently underway, overseen by UK Sport and Sport England.

The review is being led by barrister Anne Whyte, who has experience in investigating non-recent and institutional forms of abuse.

Whyte is set to investigate the period from August 2008 to August 2020.

The review will investigate the nature and volume of complaints received by British Gymnastics, including allegations of mistreatment, sexual, mental and physical abuse, bullying, harassment and discrimination.

The approach taken by British Gymnastics to resolving complaints, reasons for any delay in complaints being raised, and the adoption and application of safeguarding and complaints procedures will also be investigated.

The culture and practices of British Gymnastics, including its registered clubs, in relation to its treatment of gymnasts and consideration of their welfare will be reviewed.

Gymnastics New Zealand and the Royal Dutch Gymnastics Union have announced similar independent review processes in recent weeks.

Allegations of abuse have emerged in the wake of the Netflix documentary Athlete A, which focused on the sexual abuse scandal in the sport in the United States.
