World cycling chiefs have vehemently denied covering up a positive drugs test by retired cycling champion Lance Armstrong, following claims by his disgraced former cyclist Tyler Hamilton.
The Seven-time Tour de France champion Armstrong is currently weathering the storm of a US federal investigation into claims that his former team US Postal used public money to fund a comprehensive doping programme.
Federal investigators have travelled to Europe and beyond in a bid to gather evidence for their investigation, calling on a number of former teammates and employees of Armstrong's squad to give testimony.
Hamilton, a former teammate of Armstrong's at US Postal, told CBS television's "60 Minutes" last weekend, that Armstrong was part of a sophisticated doping program.
But the UCI has since said in a statement Armstrong has never been the subject of a cover-up.
