PARIS, Oct 9, 2007 (AFP) - Japanese driver Kazuki Nakajima will make his Formula One debut for Williams at the season-ending Brazilian Grand Prix on October 21, the British team announced on Tuesday.

The 22-year old driver, this year's GP2 series Rookie of the Year, is the team's official test and reserve driver and will replace veteran Alexander Wurz who retired from the sport on Monday.

Team principal, Frank Williams, said: "You cannot assess a driver's capability on the basis of one race but this is an ideal opportunity to develop Kazuki's experience.

"I am confident he will approach the race in a very workmanlike and focused way."

Kazuki Nakajima is the son of the retired Formula One driver Satoru Nakajima.

"I am very grateful to the team who have given me this opportunity," said the rookie.

"I hope I now know the car very well and thankfully have done some Friday driving as recently as Shanghai.

"This is a chance I intend to grab with both hands and repay the faith the team are showing in me with a strong performance."

The Brazilian Grand Prix takes place at Interlagos.
