I think this story has been going around for a while but it seems to have resurfaced. Since parting company with his dad (sacking is perhaps a bit too strong) Mclaren have been handling Hamilton's affairs but it looks like Mika could be taking over responsibility for his financial affairs. Hakkinen has some experience looking after an F3 driver through his own managment company, Aces Group.
