Formula One championship leader Kimi Antonelli remained ice-cool to win a chaotic and at times bewildering Monaco Grand Prix and extend his run of victories this season to five on Sunday.

The 19-year-old Italian built a lead of more than 20 seconds after starting from pole in his Mercedes, but that evaporated, first after a safety car was deployed and then when the race was red-flagged to repair a crumbling surface at the final corner where ?Ferrari’s Charles Leclerc hit the barriers.

After a delay of around 40 minutes while repairs were carried out near La Rascasse, the race resumed with a ?standing ?start, but just as in the day’s first start, Antonelli was unfazed as he put down eight faultless laps to ?become the youngest winner of the sport’s most iconic race.
