“It’s still under discussion, I’m afraid,” said Brawn on BBC Radio 5
Live.
“I can’t comment very much on that, but Michael’s been a huge asset to
the team, he’s really taken us forward.
“I do think Michael contributes an awful lot, so I think the decision for
Michael to stay or not continue is a difficult one.
“Obviously he’s very involved in that decision, and discussions are
ongoing at the moment.”
Asked whether Hamilton could be joining Mercedes, Brawn naturally ducked the
issue, adding: “I think any ambitious team looks at the top drivers and
we’re an ambitious team.
“But I think there’s an awful lot of speculation. We will have some
things to say in the next few weeks, next few months, and then all will
become clear.”
