World champion Max Verstappen led a Red Bull 1-2 in Sunday’s Azerbaijan Grand Prix in a potentially key moment of the title race after pole-sitter Charles Leclerc and Ferrari endured another dose of misery with a double retirement.

Sergio Perez had jumped Leclerc to the first turn before Verstappen took control as the Ferraris of Carlos Sainz and then Leclerc retired with engine problems. George Russell took third ahead of teammate Lewis Hamilton who needed a helping elbow to climb out of his cockpit such was the state of his back after an afternoon being jolted around his bouncing car.
