Button and Paddy Lowe congratulate Vettel in the drivers room before going out on the podium, but it's not all smiles. Button says "Didn't you see me at the restart?" Before Vettel replies with "You were just behind weren't you?" Button's response is "Half way alongside. Come on...is that how we're racing now?!" Vettel still has a dig about Button's restart before there ushered out on to the podium

More smiles on the podium though, as Button holds the winning trophy aloft. A big cheer for Button who is a popular winner. Vettel throws his trophy in the air as he salutes, and this time Button congratulates him again.

Three world champions on the podium together, and Vettel seems delighted to have closed it out. He stays out a moment longer to salute the crowd.

As the sun sets in Suzuka the drivers leave the podium. Congratulations to Sebastian Vettel, a hugely deserving champion, and the ninth double World Champion in Formula One history. Congratulations too go to Jenson Button for a very strong drive and his third win of the season, while Fernando Alonso also deserves a mention for his part in the chase to the flag.

So, we have the 2011 World Champion confirmed, but there's still four races to go and more great racing to look forward to. It was a fantastic race, thanks for joining us and stay on the site for the full reaction to Button's win and Vettel's world title.
