Renault have been suspended from the European Grand Prix in Valencia after the pit crew seemingly failed to attach Alonso's right front wheel correctly and it bounced across the track at the Hungaroring on Sunday.

Race stewards ruled that  that Renault "knowingly released car no. 7 from the pitstop position without one of the retaining devices for the wheel-nuts being securely in position, this being an indication that the wheel itself may not have been properly secured."

"Being aware of this Renault failed to take any action to prevent the car from leaving the pitlane....failed to inform the driver of this problem or to advise him to take appropriate action given the circumstances, even though the driver contacted the team by radio believing he had a puncture."

Renault is expected to appeal.
