Lance Stroll has been confirmed as a Force India driver for next season.
The Canadian's move from Williams has been an open secret since his fashion billionaire father, Lawrence Stroll, led a buyout to take over Force India in August.
Stroll, 20, leaves Williams after two seasons with a podium finish at last year's Azerbaijan Grand Prix, one of few highlights.
He replaces Esteban Ocon, who will be the reserve driver for Mercedes next year, to team up with Sergio Perez.
"This is the beginning of an incredibly exciting journey alongside a successful team with a great culture," said Stroll.
"It's a new challenge and I am excited to embrace this new opportunity."
Force India team principal Otmar Szafnauer added: "I'm pleased that we can finally confirm Lance's arrival to race alongside Sergio next year.
"It gives us an exciting line-up with the perfect blend of youth, talent, and experience.
"We see huge potential in Lance and believe we can create an environment in which he can flourish.
"Our team has enjoyed great success nurturing and developing young and talented drivers, and we are very excited to begin our journey with Lance."
British rookie George Russell will race alongside the returning Robert Kubica at Stroll's former team Williams next year.
