GP2 Series champion Nico Rosberg will race for Williams in Formula One next season, the team confirmed this morning.
German driver Rosberg has impressed as a Williams test driver and recently signed a long-term contract with the team, putting him in pole position to partner Mark Webber in 2006.
Williams today confirmed Rosberg, son of former world champion Keke, as a race driver next season, filling the void left by Jenson Button's decision to buy his way out of a long-term deal.
Rosberg said: "For quite a few years, I kept a number of options open, such as continuing my education, but this announcement is the validation after ten years of racing that I have chosen the right direction.
"Winning the GP2 title this season, especially given the competition, was a satisfying achievement, but of course this development is the crowning glory of a great year.
"I am really looking forward to starting work at the end of this month and learning as much from the team as I possibly can."
Frank Williams added: "I believe I am one of many in Formula One who is genuinely excited about the prospect of Nico Rosberg.
"Given the attention he commands, I am delighted he has signed with us for next season."
Rosberg became the youngest driver in history to drive a Formula One car when he tested for Williams in 2002.
