Under F1’s regulations, competitors must ensure that a 1.0 litre sample of fuel can be removed from their car at any time during the event.

But Vettel was referred to the stewards by the FIA’s F1 technical delegate Jo Bauer because “it was possible to take only a 0.3 litre sample” from the German’s Aston Martin.

Exclusion from Sunday’s race means Vettel has lost his second-place finish and his second podium for Aston Martin.

The four-time world champion narrowly missed out on his first win in two years to Esteban Ocon, who claimed a shock maiden victory for Alpine.

Vettel’s disqualification has had a big impact on the final classification from the Hungarian GP, with world championship leader Lewis Hamilton promoted to second.

Carlos Sainz now completes the podium in third for Ferrari, while every other driver moves up one position.

Significantly, Red Bull’s Max Verstappen gains an extra point for moving up to ninth, while Kimi Raikkonen has been promoted into the top-10 for Alfa Romeo.

Hamilton now holds an eight-point advantage over Verstappen heading into F1’s summer break.
