Formula Two chiefs found Israeli driver Roy Nissany "wholly responsible" for the horror crash that saw a rival driver land on top of his car in Sunday's British Grand Prix.

Nissany, a 27-year-old who races for DAMS and is a member of the Williams driver academy, escaped largely unscathed from the dramatic incident thanks to the Halo driver protection device on his car.

Moments after making an error and running wide at Silverstone's Stowe corner, Nissany's DAMS made contact with the Prema Racing car of 19-year-old Norwegian Dennis Hauger, who was knocked off the track, before Nissany shuffled back into the pack.

His driving was heavily criticised by race bosses, and it almost had disastrous consequences when Nissany turned the Vale sharp corner that followed, as Hauger's out-of-control car came bounding over a kerb and landed on top of the DAMS that had just knocked the teenager off course.

Fortunately for all concerned, there was no tragic outcome.

Nissany wrote on Twitter: "Thank you all so much for the concern. I'm ok, it’s part of racing and luckily the halo was there for me. We'll recover and come back stronger for Austria."

Yet Formula Two race stewards imposed a punishment that will take effect in next week's race at Spielberg, handing Nissany a five-place grid penalty and saying he had "fully accepted blame".

In a statement, they said: "Having considered the matter extensively, the stewards determined that car 16 [Nissany's DAMS] left the track at turn 15 after making an error.

"The driver rejoined the course at the exit of the corner and rather than focusing on a safe merge into traffic, made an unpredictable and unsafe move to defend his position that initiated the contact with car 1 (Hauger's Prema). Car 16 was wholly responsible for the collision and fully accepted blame for the incident."

The stewards' statement confirmed the five-place grid penalty for next week in Austria.
