Antonelli wins again to capitalise on Russell retirement in Canada

George Russell suffered a major blow to his title hopes as retirement from the lead of the Canadian Grand Prix handed victory to team-mate Kimi Antonelli.

The two Mercedes drivers had staged a gripping battle for the lead, swapping places several times, and were still nose to tail when Russell's car suddenly stopped on lap 30.

Antonelli's fourth win in a row, coupled with Russell's retirement for what Mercedes said appeared to be a power-unit problem, puts the Italian 43 points ahead in the championship - seven points off two clear wins.

Russell's retirement was not only a bitter blow to the Briton, but it also robbed the race of a no-holds-barred battle between the two Mercedes drivers, the second in two days after a dispute during the sprint on Saturday.

For the second day in a row, Antonelli complained about Russell's driving, accusing him of pushing him off the track.

And shortly before Russell's race ended, both drivers had been warned to keep the racing "tidy" or they would be told to hold position.

Before that, there had been several laps of frantic action and Antonelli appeared to have a pace advantage at the time Russell retired.

With Russell out, that paved the way for Lewis Hamilton and Max Verstappen to contest second place - and Hamilton overtook his old rival in the closing stages to snatch it.

The key stories of a thrilling race were:

The racing rivalry between Antonelli and Russell started immediately. Russell made a slow start from pole, Antonelli passed his team-mate, and McLaren's Lando Norris swept by both Mercedes into the lead from third on the grid.

Norris, who had started the race on intermediate tyres, pitted on lap two, leaving Antonelli initially leading a five-car train of Russell, Hamilton's Ferrari, Verstappen and the second Ferrari of Charles Leclerc.

Russell soon began to apply pressure on Antonelli and the Briton took the lead at the final chicane on lap six, Antonelli being forced to take evasive action through the run-off area as they entered the corner side by side.

Russell appeared relatively comfortable in the lead for a few laps, until he locked up his front brakes into the hairpin on lap 12, allowing Antonelli to get pass him - only for Russell to reclaim the lead into the final corner.

Antonelli tried again into the first corner and had to back off, but now Russell could not shake off his team-mate.

Four laps later, Russell again ran deep into the hairpin and they went side by side into the final chicane, only for Russell to hold on again.

Five laps went by before Russell again locked up at the hairpin and Antonelli passed for the lead down the straight towards the final chicane, only to make his own mistake at the hairpin two laps later and let Russell back into the lead.

Antonelli came back at him on the outside into the chicane and was slightly ahead as they turned in, but he had to take to the run-off area.

Returning to the race in the lead, Antonelli was ordered by the team to give the place back because he had passed off the track.

Antonelli complained, saying: "Why? He pushed me off." But he did what he was told, before trying again at the chicane, only for Russell to hold him off.

This was the point at which both drivers were effectively told to cool it by the team, and the fight calmed down considerably before Russell's retirement.

McLaren's race began to unravel even before the action got under way.

Both drivers took to the start on the treaded intermediate tyres, despite a dry track, hoping to benefit from the cold conditions.

But through two aborted starts caused by Arvid Lindblad's Racing Bulls failing to go into gear, Oscar Piastri twice asked to pit for slicks before the start had even happened, saying the inters were "a mistake".

His engineers turned down the request, and the McLarens stuck with the inters, Norris using their extra warmth and poor starts from both Mercedes to take the lead.

But the tyres were soon past their best and Norris had to stop at the end of lap two, Piastri having already chosen to do so at the end of the first lap.

Norris made good progress through the field, moving up to ninth place before being told to pit - the team had to clear debris from a cooling duct.

That dropped him down the field again and his race came to an end with a suspected gearbox failure on lap 39.

By then, Piastri had already caused himself further trouble because of a clumsy collision with Williams' Alex Albon, for which he was given a 10-second penalty.

McLaren's problems meant second place came down to a tussle between the two most successful active drivers in F1.

Verstappen initially trailed Hamilton's Ferrari but passed with an audacious move into the first corner on lap 13.

The Red Bull moved clear of Hamilton, but in the second part of the race, helped by two virtual safety cars, the seven-time champion was back on Verstappen's tail and they went into the last 13 laps with the Ferrari less than a second adrift.

Hamilton kept asking his team for more power, but he kept his patience and at the start of lap 62, with six to go, he finally made it through, with a delicious move around the outside of the Red Bull into the first corner.

Verstappen came back at the Ferrari, challenging into the first corner a lap later and pressured him for the rest of the race, but Hamilton held on for his best result for Ferrari in a grand prix, and Verstappen took his first podium of the year in third.

Hamilton's team-mate Leclerc took fourth after a subdued weekend, and a race in which he had a massive moment out of the final chicane but managed to hold the car without spinning.

Leclerc was so frustrated that with about 25 laps to go he asked his engineer for no more communication until the final lap unless it was for something urgent.

Red Bull's Isack Hadjar took fifth place despite a late stop-and-go penalty for a yellow flag infringement, ahead of Alpine's Franco Colapinto, Racing Bulls' Liam Lawson, Alpine's Pierre Gasly, Williams' Carlos Sainz, and the Haas of Oliver Bearman who took the final point in 10th.
