F1:'Jenson Button to announce his F1 retirement at the Japanese GP'

Jenson Button is set to announce his retirement from F1 at this weekend's Japanese Grand Prix, according to reports.

The Times, the Daily Mail and The Daily Telegraph all believe Button has decided to exit on his own terms and he regards the native country of his wife Jessica - a place which has become a second home for the Englishman - as the ideal venue to confirm he will leave the sport at the end of the season.

A mixture of doubt surrounding his 2016 race seat and the competitiveness of the McLaren-Honda package are thought to be behind Button's decision.

After spending the winter of 2014 waiting to see if he would be retained, it seems the 2009 world champion would prefer to walk away rather than suffer the indignity of being snubbed by the team in favour of one of their junior drivers.

Asked about his future ahead of the Singapore GP, Button told Sky Sports F1: "It's a tricky one. When you ask the question it is always funny because I've been racing for so many years in Formula 1 and you get emotional about the question because even if it is your decision or the team's decision to race in F1 next year you still get emotional because it has been your life for so long.

"I always wanted to end my career on a high, but I also wanted it to be my decision when I retired. So it is a real tricky one, but at the moment this weekend I can't think about it anymore, I need to get my head down and race then I can think about it a bit more before Suzuka. Hopefully we can decide what the best thing for the future is for the team and myself."
