Chris Froome's bid for a record-equalling fifth Tour de France title got off to a shaky start on Saturday after a dramatic crash left him around 50 seconds down on rivals, Fernando Gaviria claiming the yellow jersey after a bunch sprint rounded off the first stage.

With just 6 km to the finish, Froome went flying over a barrier and landed on a grassy verge, emerging seemingly unhurt as the peloton sped off to a frenetic sprint where Quick Step's Gaviria edged Peter Sagan and Marcel Kittel.
