MONACO: Formula One championship leader Kimi Antonelli stayed ice-cool to win a chaotic Monaco Grand Prix and extend his run ​of victories this season to five on Sunday.

The 19-year-old Italian built a commanding lead after starting from pole in his Mercedes but that evaporated after a late red flag to inspect a crumbling surface at the final corner following a crash that took out Ferrari’s Charles Leclerc.

After a ‌delay of ‌around 40 minutes while repairs ​were ‌carried ⁠out, ​the race ⁠resumed with a standing start but Antonelli remained unfazed as he became the youngest ever winner of the iconic race.

Ferrari’s Lewis Hamilton was runner-up for the second successive Grand Prix with Red Bull’s Isack Hadjar provisionally third, although he was one ⁠of a number of drivers under investigation ‌for a variety of ‌infringements.

Hamilton, who equalled the late ​Ayrton Senna’s eight Monaco ‌podiums, moved above Antonelli’s team mate George Russell ‌into second place in the standings, 66 points behind Antonelli.
