Operación Puerto doping case
Liberty Seguros sponsored the UCI ProTour cycling team, Liberty Seguros – Würth, but dropped the sponsorship on 25 May 2006 due to the Operación Puerto doping case, involving the team manager Manolo Saiz. They also sponsored a smaller continental cycling team based in Portugal, but dropped the sponsorship for this also in September 2009, when three members of the team failed drugs tests simultaneously.
