Jenson Button's future remains in doubt with reports the 2009 Formula One world champion went on a tour of McLaren's factory in Woking yesterday.

Button and his manager Richard Goddard were reportedly shown around the facility by McLaren principal Martin Whitmarsh.

Button, who has stalled on signing a new deal with the Brawn GP team, could yet link up with Lewis Hamilton at McLaren. A spokesman for McLaren told The Guardian: "Having just arrived at Heathrow, Jenson made a small detour to Woking to say hello."
