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.
