Qualifying is complete for the Mexican Grand Prix and an exciting grid is set for race day after Max Verstappen's dominant start to the weekend came to an abrupt end.
Favourite to take pole position having been fastest in all three practice sessions, the Red Bull star was instead beaten to pole by Ferrari who took a shock front row lockout headed by Charles Leclerc and Carlos Sainz.
It proved to be a dramatic session right from the very start though, with Max Verstappen and George Russell under investigation for pit-lane infringements.
Mercedes had another car under investigation too with stewards looking at Lewis Hamilton for not slowing down enough under yellow flags.
There was a major casualty from the first qualifying session, though with McLaren star Lando Norris out in Q1 after failing to complete a clean lap and then hitting a yellow flag on his final run preventing him from going faster.
