Contador, the Tour winner in 2007, 2009 and 2010 who tested positive for the banned anabolic agent clenbuterol, also faces losing his 2011 Giro d'Italia title and all the other victories he claimed last season.

Contador, who has 30 days to appeal to the Swiss federal court, is to hold a news conference on either Tuesday or Wednesday.

The Spaniard's Tour title will be handed to Luxembourg's Andy Schleck, with Bradley Wiggins becoming the first Briton to climb on to the podium and Russian Denis Menchov finishing second.
