Kimi Raikkonen given penalty for Russian GP Valtteri Bottas clash

The loss of six points for Ferrari allows Mercedes to officially clinch the 2015 Formula 1 constructors' championship.

Raikkonen hit Bottas's Williams while challenging for third place on the final lap, after both had passed Sergio Perez's Force India as its tyres faded.

The collision sent Bottas straight into the barriers and out, while Raikkonen nursed his damaged car over the line in fifth place.

The stewards decided the move deserved a 10-second stop/go penalty, which was applied as a 30s time penalty post-race.

Raikkonen was adamant the collision was a racing accident and that a penalty would not be fair.

"I overtook him there once before and I wasn't too far back so I thought I would try again," he said.

"Once I decided to try I can't back off. I don't know if he didn't see me at all or didn't expect me to go there.

"I tried to turn as much inside as I could but there was nowhere to go and we collided."

But Bottas replied: "I don't think it was a racing incident.

"I didn't see anyone there and I was in front, and then suddenly someone hits me."

Raikkonen's penalty elevates Daniil Kvyat into fifth place for Red Bull at his home grand prix.

In a further post-race penalty, McLaren driver Fernando Alonso has had 5s added to his race time for corner cutting at Turn 16, which he received a warning for during the grand prix.

That costs McLaren a point as he falls to 11th behind Max Verstappen's Toro Rosso.
