Shane Sutton has resigned as British Cycling technical director.
The 58-year-old Australian tendered his resignation after another day of allegations of discrimination. Here we look at the key points with the Rio Olympics 100 days away.
Why has Shane Sutton resigned as British Cycling technical director?
London 2012 Olympian Jess Varnish alleged Sutton made sexually derogatory remarks, telling her to "go and have a baby" after she was dropped from the team. Ten-time Paralympic medal winner Darren Kenny said Sutton's conduct towards the para-cycling squad was "abysmal", and it was claimed he called the riders "gimps". Malaysian cyclist Josiah Ng alleged Sutton called him 'Boatie', which could be interpreted as a reference to people sailing from Asia to seek asylum in Australia.
How does he respond to the allegations of discrimination?
Sutton refutes the claims made by Varnish and Kenny and said he was looking forward to addressing them in the independent review British Cycling announced on Tuesday. It will be held in conjunction with UK Sport. Sutton declined to specifically address Ng's comments.
What happens next?
Wednesday marked 100 days to go until the Rio Olympics and Sutton quit. In announcing his resignation, he insisted: "I look forward to taking a full part in the review process so I can respond to the allegations in detail." The terms of reference and the persons responsible for the independent review were still to be announced on Wednesday afternoon.
Who is in charge now?
Andy Harrison, programmes manager of British Cycling, has taken over with immediate effect. He will work closely with head coach Iain Dyer. Harrison was performance operations manager for the English Institute of Sport (EIS) and joined British Cycling in May 2013. He was at EIS for 10 years and previously worked for England Netball and as the British women's water polo manager for the London 2012 Olympics.
What does it mean for medal chances in Rio?
Medal chances remain good, but squad morale may have taken a big hit as Sutton is a popular figure among many riders. Sutton was lead figure on the selection panel and an ally of Mark Cavendish, who was slated to ride the six-discipline omnium and be a reserve rider in the team pursuit in Rio. Cavendish's selection may now be in doubt without Sutton's influence.
