Bradley Wiggins' use of therapeutic use exemptions (TUEs) made little difference to the outcome of the 2012 Tour de France, according to Shane Sutton.
Wiggins' TUE record was leaked last month by a Russian hacking group calling themselves Fancy Bears, who were able to access records belonging to the World Anti-Doping Agency.
A five-time Olympic gold medallist, Wiggins has since defended his use of TUEs as completely legal, although fellow cyclist Tom Dumoulin has claimed the case "stinks".
Despite criticism from some quarters, Wiggins - who prevailed ahead of Team Sky team-mate Chris Froome by more than three minutes on the 2012 Tour - would have won anyway according to British Cycling's former technical director Sutton.
"Most definitely, for sure [he would have won]," Sutton told Sky Sports.
"I don't see Brad as gaining an advantage by doing what he had to do.
"He was suffering at the time and obviously he was given a TUE to get him back to where he would normally be at and to cope with the conditions that were going to prevail.
"At that time of year his allergies would be at their height and, as far as I am concerned, Brad just got out there and did the business.
"The authorities say there has been no wrongdoing here."
British Cycling on Friday upheld claims by Jess Varnish that Sutton, who resigned in April, used "inappropriate and discriminatory" language towards her.
Sutton has always denied any wrongdoing.
