Sir Dave Brailsford wants cycling's world governing body to intervene in an effort to prove Tour de France leader Chris Froome is cleanRead the full story ›
Chris Froome claimed he was drenched in urine and called a "doper" after enhancing his Tour de France lead on a 14th stage won by fellow Briton Steve Cummings.
Froome (Team Sky) now leads nearest rival Nairo Quintana (Movistar) by three minutes 10 seconds, with his dominance bringing about innuendo and abuse.
The 30-year-old insists he is a clean rider.
He told ITV4: "A spectator threw a cup of urine in my face and said 'doper'."
Froome added: "You don't do that to anyone. It's not in the name of sport.
"That's extremely disappointing. Unfortunately I think a lot of the reporting on the race has been very irresponsible.
"What can I do? I can get angry. I'd rather keep my composure and stay focused on the race."
MTN Qhubeka's Steve Cummings claimed a stunning smash and grab win on stage 14 of the Tour de France to Mende on Saturday.
The 34-year-old from the Wirral claimed African squad MTN-Qhubeka's first Tour stage success after powering past Frenchmen Thibaut Pinot (FDJ) and Romain Bardet (Ag2r La Mondiale) in the finishing straight.
The 178.5-kilometre route from Rodez finished at Mende airstrip after the punishing 3km ascent of the Cote de la Croix Neuve.
Cummings had been part of the day's 20-man escape group and stayed in touch as Bardet led Pinot over the summit before the near 2km run-in along the flat to the line.
And there Cummings, in his third Tour, took his chance.
Cummings rode for Team Sky in 2010 in support of Bradley Wiggins and in the 2012 Tour, riding for BMC Racing's Cadel Evans.
Team Sky leader Froome had anticipated attacks on his near three-minute advantage, but instead enhanced his lead as he fended off Nairo Quintana.

Chris Froome powered to victory in Stage 10 of the Tour de France and extended his overall lead in the race for the yellow jersey in an extraordinary fashion.
The 2013 winner started the day as favourite ahead of Nairo Quintana and attacked on the brutal climb with 6km to go - leaving the Colombian in his wake and seemingly powerless to catch him.
Quintana struggled to keep pace with Team Sky's main man, and was eventually overtaken a few hundred metres from the finish line by Froome's teammate, Ritchie Porte.
Froome now leads Porte by 59 seconds in the general classification and Quintana by 1min 4secs.
