Nico Rosberg is to stay on alongside Lewis Hamilton at the Mercedes team next season, BBC Sport can reveal.
The 28-year-old German’s contract was due to expire at the end of the 2014 season, but it has been extended for at least two years.
A Mercedes spokesman said: “We have long-term relationships with both our drivers.”
Englishman Hamilton is in the second season of a three-year deal with Brackley-based Mercedes.
