Jonathan Tiernan-Locke questions Team Sky TUE stance
Team Sky's stance in allowing Sir Bradley Wiggins to take a banned drug to treat his asthma has been questioned by one of their former riders.
Jonathan Tiernan-Locke, who rode for Team Sky until he was sacked for a doping violation in 2014, says the matter has tainted the outfit's image.
Wiggins was granted a therapeutic use exemption (TUE) to take triamcinolone before his 2012 Tour de France win.
TUEs let athletes take prohibited substances if there is a medical need.
In an exclusive interview with BBC Sport, Tiernan-Locke - once tipped as a possible heir to Wiggins - claims Sky have been less than transparent about the use of TUEs.
Tiernan-Locke, now 31, also discusses his own troubles, insisting he is "100%" innocent of doping despite being handed a two-year ban for irregularities in his blood passport.
