Newly crowned F1 world champion Jenson Button will be a McLaren driver in 2010, BBC Sport is reporting.

Button has been linked to McLaren for a number of weeks now and it now seems the Englishman has agreed terms that will see him link up with fellow countryman and 2008 World champion, Lewis Hamilton.

Although the switch from Brawn has not yet been made official, the BBC adds that an announcement will be made later today.

If the deal does go through, it will lead to the creation of an all-British F1 super team, and while McLaren is a top outfit, Button's choice will surprise many in the sport.

Indeed Sir Jackie Stewart had urged the 29-year-old to stick with Brawn rather than move to McLaren.

"If I was Jenson, I would stay with Brawn," Stewart told The Guardian earlier this week. "He knows the team, he is comfortable there and Ross Brawn's reputation is outstanding.

"Going to McLaren will mean putting his head into the tiger's den with Hamilton already established there. That would be a huge challenge. I think he is in the best position where he is."

Sir Stirling Moss and Niki Lauda meanwhile echoed those thoughts: "It would be a big risk for Jenson to go into the McLaren team head-to-head with Lewis," Moss added. "He might find himself beaten by Lewis, who I think is possibly the fastest driver out there."

"Jenson needs to be very certain that he wants to go into a team which Hamilton has very much made his own," Lauda continued.

"If the money is involved is about the same, or even slightly less, than Jenson should stay with Brawn."
