London 2012 Olympics: Team GB wrestler Myroslav Dykun banned for two years for doping Chief executive of UK Anti-Doping, Andy Parkinson, said: "Our pre-Games prevention programme was put in place to ensure that only clean athletes represent Great Britain and this case proves that the system is working. When the eyes of the world fall on London later this month, we want the public to have confidence in clean sport and understand that doping of any kind will not be tolerated. Olga Butkevych, who was also born in Ukraine, will be Britain's sole wrestling representative at the London Olympics after the British Olympic Association rejected pleas from British Wrestling to relax its selection guidelines to allow three athletes to compete at the Games. The wrestling governing body had hoped the BOA whould show leniency towards Britain's wrestlers after they failed to fulfil the necessary criteria to ensure selection for the Olympics, but the panel refused to amend its guidelines. Britain's last Olympic medal in the sport was in 1984 when Noel Loban won bronze in Los Angeles.
