Team Sky have denied any wrong doing on their part following claims by the Daily Mail that a medical package was delivered to the team in France on June 12th 2011.
In a press statement, Team Sky said: "Team Sky was contacted by the Daily Mail regarding an allegation of wrongdoing.
We take any issues such as this very seriously and immediately conducted an internal review to establish the facts. We are confident there has been no wrongdoing.
We informed British Cycling of the allegation and asked them to contact UKAD, who we will continue to liaise with.
Team Sky is committed to clean competition. Our position on anti-doping is well known and we 100 per cent stand by that."
