Weir, who failed to win any medals at the Brazilian Games, has also reiterated how he will never represent Britain again after the "belittling" and "hurtful" remarks from coach Jenni Banks.

This came after his poor performance in the heats of the T53/54 4x400 metres relay led to the British team failing to qualify for the final.

Weir, who was competing alongside Nathan Maguire, Richard Chiassaro and Moatez Jomni, clocked a time around 10 seconds slower than he had posted at the European Championships earlier in 2016.

“I came off the track, and she came running over and accused me of sabotaging the team and doing it on purpose,” he told The Guardian.

“She said I was a disgrace to the country.

“To be accused of not putting in 100 per cent during a race, it made me feel like s***.

“There was a few words thrown back and forwards, a lot of the teams saw what went on, and they were absolutely disgusted with the way she spoke to me. 

"I have not talked to her since.”

Banks was appointed in 2013 ahead of Weir's long-term coach, Jenny Archer.

Weir, who claimed four gold medals on home turf at London 2012, also alleged earlier this month that she threw his £3,000 ($3,700/€3,500) carbon fibre chair across a room during a row.

However, he has now said that he cannot confirm whether this happened as he did not see the incident first-hand.

A British Athletics disciplinary panel last week cleared Banks of any wrongdoing over this specific incident.

Banks has not yet commented publicly.

“The relay didn’t go to plan, but to be honest my [wheelchair] set-up all week wasn’t right," Weir added.

"At the last minute I also changed my gloves, as I felt I was getting more grip and power, but it didn’t work. 

"I just didn’t get any power, I couldn’t pick my speed up.”

It had initially been hoped that he would make July's World Para Athletics Championships in London his final swansong.

But the London Marathon on April 23 is now set to be the last race of the 37-year-old's illustrious career.

“We can confirm there was a frank exchange of views between an athlete and the relay coach following the race when the GB men’s wheelchair team failed to qualify for the final,” said a British Athletics spokesperson. 

“We can also confirm we have met with David Weir to receive first hand his feedback on his experiences in Rio, and that we are working to ensure we learn from these experiences ahead of future team events.”
