Lewis Hamilton disqualified from Brazil F1 qualifying

Mercedes pair to start sprint race from back of grid

Hamilton stripped of P1 for technical infringement

Seven-time world champion Lewis Hamilton has been disqualified from qualifying for the Formula 1 Brazil Grand Prix after scrutineers revealed a technical infringement on his Mercedes car.

The Briton had set the fastest lap in qualifying on Friday, but his car was later found to have violated a rule relating to the rear wing.

As a result, Hamilton and his Mercedes teammate, Valtteri Bottas, will both start the sprint race from the back of the grid.

The disqualification is a major blow to Hamilton's hopes of winning a record-breaking eighth world championship.

The sprint race will take place on Saturday, with the main race scheduled for Sunday.
