It may mean a delay in the race start or it could clear up and/or avoid the Circuit Gilles-Villeneuve. Any news on start times as we get it!Lewis Hamilton and Isack Hadjar during the drivers parade at the Circuit Gilles-Villeneuve, Montreal. Photograph: Bradley Collyer/PAPreambleHold on, is that the sight of sparks flying in the Mercedes garage? Metaphorically, of course. George Russell and Kimi Antonelli have played the roles “the gent” and “tenacious teen” for the first four races of this F1 season. But with it becoming increasingly clear that it’s likely to be a straight shootout between the teammates for the drivers’ title, we’ve seen the first flash of friction between the pair in Montreal.A clash during the sprint race when Antonelli attempted to overtake Russell left the Italian fuming and Toto Wolff had to intervene, telling him to “stop the radio moaning”. Russell held on for victory, Lando Norris splitting the Mercs, though it’s a Russell-Antonelli front row for today’s race after the Briton pipped his teammate by six-hundredths of a second in qualifying.Antonelli, the championship leader by 18 points, has won the last three races of a stop-start season. But Russell likes this track – it’s his third pole in a row here. Plus there’s a 60% chance of rain and a chasing pack including Norris and Oscar Piastri in third and fourth, Lewis Hamilton starting fifth and Max Verstappen rounding off the top six.
