Reigning world champion Max Verstappen headed an incident-packed first practice session for Formula 1's Azerbaijan Grand Prix, which was red flagged for crashes by Charles Leclerc and Franco Colapinto.

Upon exiting the pits McLaren's Oscar Piastri relayed conditions were "very, very low grip' on the 6km city loop.
