Richard Kilty has admitted to being left 'heartbroken' after Team GB were stripped of their men's 4x100m sprint relay Olympic silver medals from the Tokyo Olympics.
The Court of Arbitration for Sport (CAS) made the decision to strip Team GB of their medals after CJ Ujah's doping violation.
Ujah tested positive for banned substances Ostarine and S-23 in August last year and it has since been confirmed today that the quartet - which also included Zharnel Hughes, Richard Kilty and Nethaneel Mitchell-Blake must also return their medals.
Other than Ujah himself, Kilty is the only other one to have spoken out, and lifted the lid on the personal devastation he now must face.
"It's heartbreaking to finally hear the news that the medal is going to be stripped, it's going to be wiped from history," Kilty told BBC Radio Tees .
"When it initially came out (last August), I'd only arrived back in Teesside from Tokyo for two days and the news broke he'd failed the test.
"And since then it's been very, very confusing for me, my family and the British team. The happiness for me was winning an Olympic medal and giving it to my son.
"And my motivation all through 2021 was to win an Olympic medal and give it to my son, because he's in school now, and for him to take the medal into school and say, 'Look my dad's won an Olympic medal'.
"And I never got to do that, because by the time he'd started school the announcement had come.
"So the motivation is for the next two-and-a-half years to make sure that job gets done properly this time."
Following the decision, Ujah released a statement of his own, in which he revealed that he 'unknowingly' consumed the illegal substance.
He said: "I accept the decision issued by the Court of Arbitration for Sport today with sadness.
"I would like to make it clear that I unknowingly consumed a contaminated supplement and this was the reason why an anti-doping rule violation occurred at the Tokyo Olympic Games.
"I sincerely regret that this has inadvertently led to the forfeiture of the men’s 4x100m relay team’s Olympic silver medals at the Tokyo Olympic Games."
British Olympic chiefs were left fuming after Ujah's positive drugs test finally saw Team GB stripped of their sprint medal.
A statement from the British Olympic Association read: "The BOA takes the strongest possible line against doping and those who practise it in sport - knowingly or otherwise.
"We are incredibly disappointed that we find ourselves in this position today, following confirmation of Chijindu Ujah's positive sample, taken at the Tokyo 2020 Olympic Games.
"We have always been unequivocal and consistent in our stance against doping. All athletes, wherever they are from, deserve to go to the start line knowing they are in clean competition.
"It is with deep sorrow that colleagues and opponents of Ujah were not able to be reassured of this fact in Tokyo.
"Having spent the last few years retrospectively awarding numerous British athletes with medals they should have won on the day at Beijing 2008, London 2012 and Sochi 2014, we understand first-hand the hurt and loss doping can cause.
"On behalf of everyone in British sport we unreservedly apologise to the athletes whose moment was lost in Tokyo due to the actions of Ujah."
