The review, which took place in 2012, contained anonymous statements compiled by former British Cycling chief executive Peter King.

Cycling is one of Britain's most successful Olympic sports and will receive nearly £26 million ($32 million/€31 million) of public money from UK Sport for the Tokyo 2020 cycle.

British Cycling, however, has faced allegations of sexism and bullying with another report, spearheaded by British Rowing's chairman Annamarie Phelps, due to be published.

"We did not receive [an accurate] King report," said Nicholl.

"We were given to believe that actually we had a very light-touch version of it fed to us at UK Sport, so we had no indication of the significance of that report.

"It's only now come to light.

"That's a complete lack of transparency and that's a relationship that is not acceptable in terms of what was shared with us as opposed to what the actual facts of that report were."

Brian Cookson, the President of the International Cycling Union and who led British Cycling at the time of King's report, said he would not comment until Phelps' findings are revealed.

A British Cycling statement said: "Contributions [in the King report] were made with a guarantee of anonymity, so key findings and recommendations were shared in briefings with UK Sport and the British Cycling Board.

"The full report was also made available to the 2016 independent review, jointly commissioned by UK Sport and British Cycling in April last year, of the world class programme."
