Media reports about doping in British sport will not harm Russia, Dmitry Shlyakhtin, head of the Russian Athletics Federation, was quoted by R-Sport news agency as saying on Sunday. UK Anti-Doping (UKAD) said it was 'deeply concerned and shocked' by reports a British doctor alleged he had prescribed banned performance-enhancing drugs to 150 sports figures including several Premier League footballers. UKAD has been processing some Russian doping tests since Russia's own anti-doping agency was embroiled in a mass cheating scandal last year. Shlyakhtin said not all Russian doping tests were sent to the UKAD laboratory.
