Sean Yates leaves Team Sky and announces retirement
Team Sky sporting director Sean Yates has retired from cycling after three decades in the sport.
Yates had held the role since 2010 and was instrumental in Sky's Tour de France success in the summer.
Sky said Yates's decision was not related to doping, despite the team's zero-tolerance approach to drugs.

Losing Sean Yates, like this, is a huge blow for Team Sky. While he may have upset a few riders last year, he did what he was asked to do: get Bradley Wiggins in yellow. He will be missed. But there are also implications for the team's 'zero tolerance' anti-doping policy. That few in the sport are buying Yates's denials is one thing; that a growing number are questioning the credibility of Sky's holier-than-thou recruitment process is far more damaging.
Yates added: "I realise the timing of my retirement will lead to speculation but I can walk away with my head high knowing I have done nothing wrong."
