The chief executive of Welsh athletics Matt Newman has insisted that there is not a drug problem with his team after Rhys Williams became the second Welshman to fail a drug test ahead of the Commonwealth Games.
"I don't think there is a problem in Welsh athletics," Newman told the South Wales Argus. "We take our responsibility seriously and we have been a clean advocate of a clean sport.
"We have a close relationship with UK athletics and anti-doping agency and made sure there is a comprehensive education in place from the academy athletes up to the international."
Williams is the son of former rugby player JJ Williams.
