Jenson Button has urged McLaren to decide if they are going to retain him as a driver for the 2016 Formula One campaign “in the next few weeks”.

The 35-year-old British driver had to wait until December of last year before being notified that he would be kept on to race alongside new team-mate Fernando Alonso.

It meant Button’s team-mate from last year, Kevin Magnusson, returned to being a reserve driver with the Woking-based outfit.

However, following a disappointing campaign to date which has left McLaren ninth in the constructors’ standing with just 17 points and only seven races remaining, speculation has intensified over Button’s future.

Both Magnusson and Stoffel Vandoorne, who is currently dominating the GP2 class, have been mooted to be Button’s replacement in 2016 which has left the 2009 world champion wanting his team to make a decision sooner rather than later.

“I think that is something we need to discuss away from the circuit over the next few weeks,” he said. “It is always in your hands and hopefully over the next few weeks we can decide, either way.”

Meanwhile, Button is 126.00 to secure a podium finish at the upcoming Singapore Grand Prix, while current leading driver and reigning champion Lewis Hamilton is 1.53 to win the race.
