The row over a bag of drugs delivered to cycling superstar Bradley Wiggins deepened yesterday.
Bob Howden, head of British Cycling, failed seven times to provide an answer when asked what was in the bag couriered to the cyclist during a race in France in 2011.
And rather than quell suspicions, Mr Howden refused to disclose during a BBC Radio 4 interview whether evidence existed to support Team Sky principal David Brailsford's insistence that the package contained fluimucil - a the legal over-the-counter decongestant.
Questions have been raised as to why the medicine would be sent on a two-day trip from Manchester to the French Alps when Sir Bradley could simply have bought it from a local pharmacy instead.
Despite being asked at least six times about the issue, Mr Howden insisted he is prevented from saying exactly what was in the package because of a UK Anti-Doping investigation into the matter.
