Manx cyclist Peter Kennaugh has hit out at drug cheats in cycling.
The current British Road Race Champion and Team Sky rider tweeted "What a joke this sport can be! The clean riders of the peleton need to get together and push these cheats out - enough is enough".
And further - "Riders who were only "trained" by Ferrari - I mean come are you really that stupid? And do you think everyone else is too?"
It follows Tour de France winner Vincenzo Nibali's Astana team being awarded a World Tour licence yesterday - despite a number of positive doping tests in recent months.
The sports governing body - the UCI - says the licence is on probation and has also launched an investigation in to alleged links between Astana and Lance Armstrong's former doctor Michele Ferrari.
Ferrari was given a lifetime sporting ban in 2012 for his part in the Armstrong doping affair.
