Bridgestone denies withdrawal rumours

Bridgestone's tyres have been out-performed by those of French rival Michelin in the past few races, most notably in France, where the two Ferrari's were the only cars running on Bridgestone rubber to make the top 11 in qualifying.

But Hiroshi Yasukawa, Bridgestone's director of Motorsport, said: "There has never been a moment that Bridgestone has thought of withdrawing from Formula 1 since our entry back in 1997.

"We have enjoyed a very successful period in F1 with no fewer than five consecutive Drivers' and Constructors' titles being won on our tyres. F1 has played a vital tool in our worldwide brand and marketing strategies and since entering F1 in 1997, our brand awareness has increased dramatically.

"With six races remaining, this year is undoubtedly a highly competitive season. We relish this top level competition and remain as committed and as passionate about our involvement in F1 as ever. We are looking forward to a battle royale with our rivals in the second half of the season."
