Yellow jersey Bradley Wiggins was praised for calling a truce on a controversial day at the Tour de France as the race was sabotaged by spectators laying tacks in the road.

Tour de France leader Bradley Wiggins believes the sabotage of stage 14 yesterday – when tacks on the road caused a number of punctures in the peloton – showed how vulnerable riders are on the road and more severe incidents could yet occur.

The 2012 Tour de France could favour cycling’s leading climbers after the route was confirmed today.
