Kevin Magnussen has been handed a 10-second post-race penalty after the stewards deemed he was at fault for causing a collision with Renault team-mate Jolyon Palmer on the final lap of the Spanish Grand Prix.

Magnussen, on fresher soft tyres, was charging after Palmer on older hard tyres but bashed into his team-mate on the last lap at turn 13.

The stewards judged the Danish driver to be in the wrong and duly handed him a 10 second time-penalty which dropped him from 14th to 15th behind Sauber's Felipe Nasr. Magnussen has also landed two penalty points on his licence - his first two of a permitted 12.

"Car 20 [Magnussen] was on a new set of soft tyres, and Car 30 [Palmer] was on an older set of hard tyres leading the driver of Car 20 to have significantly better grip and speed," a stewards statement read. "However, the stewards determined that Car 20 could not have reasonably expected to make the corner of Turn 13 without colliding with Car 30, which was subsequently forced off the track.

"The stewards imposed the penalty referred to, which was converted to a time penalty after the race as the cars were on the last lap."
