Jenson Button says he is not yet in a position to confirm his future plans despite speculation suggesting he was primed to announcement his retirement from the sport.

Reports suggested Button was going to use the Japanese Grand Prix - Honda's home event - to formally confirm whether he will stay with McLaren or exit the sport, but he says he is still in talks with the team.

Pressed during the pre-event press conference at Suzuka, a steadfast Button - who previously said he would make his decision known by the end of September - refused to give more details about his plans.
