McLaren's Lewis Hamilton
McLaren's Lewis Hamilton has been excluded from qualifying at the Spanish Grand Prix after stopping his car out on the track at the end of qualifying .
Hamilton qualified on pole but will start from the back of the grid.
He was told to stop because there was insufficient fuel in the car for him to get back to the pits and provide a sample, as required by the rules, reports the BBC.
The stewards rejected McLaren's argument that not putting enough fuel in the car was "force majeure".
The F1 rules require the car to return to the pits with one litre of fuel on board - running less fuel gives a performance advantage.
Although in this case the advantage gained in no way accounted for Hamilton's 0.578-second advantage over second placed Pastor Maldonado of Williams, the stewards felt they had to penalise McLaren.
Their ruling said: "A team member had put an insufficient quantity of fuel into the car, thereby resulting in the car having to be stopped on the circuit in order to be able to provide the required amount for sampling purposes.
A McLaren statement said: "We accept that the stewards did not agree with our interpretation of force majeure. Our aim is now to maximise the points we can score."
