LONDON — The Williams Formula One team has signed 2009 world champion Jenson Button as an adviser, 21 years after handing him his grand prix debut.
The team said on Friday that the 41-year-old, who won his title with Brawn GP, would serve as a 'senior adviser' in a multi-year deal.
"I am so delighted to once again be able to say that I’ve signed for Williams," said Button.
"Back when I was 19, it was a moment that changed my life and, despite the fact it was over 20 years ago, I already feel like I never really left.
"Sir Frank Williams showed faith in me, which I will be eternally grateful for, and I am incredibly excited to have the chance to come back and help the team as it strives once more for success."
Williams, who changed ownership last year with the founding family selling up to U.S.-based Dorilton Capital, said Button would attend a number of races and some team events in Britain.
"Bringing Jenson back on board is another positive step to help us move forward as a team both on and off track," said newly appointed Williams chief executive Jost Capito.
He said Button's experience would "add another layer to our transformation both technically and as a business."
Williams has British youngster George Russell and Canadian Nicholas Latifi as their 2021 driver lineup. Russell has a long-term Mercedes contract and shone when he stood in for seven-time world champion Lewis Hamilton last season.
The team finished last without a point last year and have not won a race since 2012.
