Lando Norris trails Oscar Piastri by 31 points in the drivers' championship

Lando Norris led Oscar Piastri to a McLaren one-two in first practice at the Azerbaijan Grand Prix.

The familiar look to the timesheets, with Ferrari's Charles Leclerc and Mercedes' George Russell third and fourth, belied an incident-packed hour.

A red flag because of a loose kerb interrupted proceedings for about 20 minutes, and limited the disadvantage that an engine problem could have inflicted on Piastri.

Lewis Hamilton clipped the wall in his Ferrari, damaging his front wing and giving himself a front-left puncture, on his way to 12th fastest time.
