Mercedes take ownership of Brawn
German car giant Mercedes has bought the Brawn Formula 1 team in a move that is likely to see Jenson Button join McLaren as Lewis Hamilton's team-mate.
Mercedes will buy a controlling interest in Brawn, believed to be 75% but is expected to continue as McLaren's engine supplier.
Brawn, who won both world titles in their debut season in 2009, will be rebranded as the Mercedes GP team.
Nico Rosberg will be their lead driver, with Nick Heidfeld his likely partner.
Neither driver has yet been confirmed, but Rosberg, who drove for Williams in 2009 is widely known throughout F1 to have already signed for Brawn.
Button, who won the drivers' title this year, has been trying to secure a pay-rise from his £3.5m salary but it seems Mercedes is not interested in keeping him on.
He and his manager Richard Goddard visited McLaren on Friday and Button is now expected to join McLaren for a salary around double what Brawn were offering.
Button's decision is understood not to be solely about money - sources say he considers McLaren might have a more competitive car than Brawn in 2010.
Mercedes Sports boss Norbert Haug said on Sunday that he was trying to secure a drive for Heidfeld, a former Mercedes protege who has driven for BMW since 2006.
"We are speaking with Nick Heidfeld as well," Haug told DPA.
"Mercedes-Benz supports the idea of signing an experienced and capable German driver. There is however no reason to finalise the driver situation too hastily."
It is believed Ross Brawn will stay on as team principal.
