Armstrong slams Landis after accusations

The world of cycling is once again facing up to a storm over performance-enhancing drugs after Lance Armstrong and the International Cycling Union slammed Floyd Landis for accusations made by the disgraced rider.

Landis, who yesterday admitted doping during his career and made allegations against several other riders, claimed seven-times Tour de France winner Armstrong struck a deal to conceal a positive test during the 2002 Tour of Switzerland.
