Castex followed the route of the Tour de France on Saturday and spent time in a car following the race with tour director Christian Prudhomme. Tour organisers said on Tuesday that Prudhomme had tested positive.
Asked by Reuters about the contact, a representative of the prime minister’s office said: “They were both wearing masks and respecting social distancing. The prime minister is to undergo a new test, just in case.”
A Reuters photographer following the Tour de France said that Castex and Prudhomme spent several hours in each other’s company during Saturday’s stage of the race, in the Pyrenees mountain range.
