Alex Albon will return to Formula 1 in 2022 after Williams announced they have agreed a deal for him replace George Russell, who will leave the team at the end of the year for Mercedes.
Albon lost his seat on the F1 grid last season when Red Bull signed Sergio Perez. He is currently Red Bull's official test and reserve driver and has been competing in the DTM Championship.
Nicholas Latifi will remain with the team for a third consecutive season, having made his F1 debut in 2020.
"It is fantastic to be able to confirm our driver line-up for 2022 and I am delighted to be welcoming Alex to the team, along with confirming our continued relationship with Nicholas into next year," said Williams Team Principal and CEO Jost Capito.
"We are extremely excited by our new line-up, with both drivers bringing a great blend of youth and experience that will not only be a great fit for the team but also help us take the next step in our journey."
Williams have previously said they had full control over their driver line-up for 2022, unlike previous seasons when Mercedes had a say.
Capito insists the team will continue to focus on this year to secure eighth place in the Constructors' Championship, which would be their best season since 2017. Equally, Capito is excited about next year with Albon onboard when F1 introduces a new set of technical regulations.
"Alex is one of the most exciting young talents in motorsport, yet comes with a large amount of F1 experience from his time at Red Bull," continued Capito.
"His multiple podium finishes highlight his speed as a driver, and we know he will immediately feel at home with the team at Grove.
"Nicholas meanwhile has consistently impressed us over the past three years with his hard work, diligence, and positive attitude. He has continued to develop throughout his time at Williams and has grown into an impressive F1 driver, as seen by his points scoring finishes this season.
"We are now looking forward to continuing to build on our positive momentum as a team and finishing this season as strongly as possible, before turning our attentions to 2022."
