Friday news briefs from Istanbul

Buemi with injured elbow in Turkey

Sebastien Buemi is wearing a bandage on his right elbow in the Istanbul paddock.

"It was my fault," the Toro Rosso driver is quoted by Speedweek. "I was jumping over a railing and hit my arm."

Asked by a reporter if his participation in this weekend’s Turkish grand prix was ever in doubt, the young Swiss answered: "Not for a second!"

Tester Bottas drove Williams at Silverstone

Williams’ new test driver made his formula one track debut this week.

In January, the British team signed 20-year-old Finnish F3 driver Valtteri Bottas.

As well as race driver Nico Hulkenberg, he drove the FW32 car on Monday at Silverstone.

"It was a great day for Valtteri," spokeswoman Claire Williams is quoted by Finland’s Turun Sanomat, "and the team was also pleased."

Only Rosberg with own motor home in Turkey

Nico Rosberg said he will never again bring his own motor home to Istanbul.

Finland’s Turun Sanomat said the Mercedes driver is the only member of the F1 grid not to be staying in local hotels this weekend.

It means he can avoid the notoriously bad Turkish traffic jams.

But German Rosberg said: "It’s definitely the last time I do it. The transporting charges are too high compared to the benefits gained," he admitted.

Button splits with Japanese model girlfriend

Reigning world champion Jenson Button has split with his girlfriend Jessica Michibata.

British daily tabloid The Sun said the 30-year-old decided to call time on their 18-month relationship shortly after the recent Monaco grand prix.

Japanese fashion model Michibata, 25, lives in Tokyo, and a friend of Monaco-domiciled Button is quoted as saying the "logistics" of the relationship "took their toll".

"Just over a week ago Jenson reluctantly decided that his racing must be his main priority," the source added.

A spokesman for Button confirmed: "Jenson is single again. He and Jessica have gone their separate ways."
