Ross Brawn on Thursday denied speculation he is set to join McLaren as its new chief executive.
The great British team announced this week that Eric Boullier is switching from Lotus to be the new 'racing director', but the Frenchman will report to an as-yet unappointed chief executive.
Brawn, having stepped down at Mercedes, has been mentioned as the obvious candidate.
But when asked by Britain's Sky on Thursday about the McLaren speculation, the Briton responded: "I'm focused on my fishing at the moment -- no discussions, no comments.
"Come the summer I may take stock and things may change - never say never - but it's not my plan. Any approaches I've had I have replied with a polite rebuff.
"I am very flattered but simply I don't want to get involved or engaged," Brawn insisted.
