After months of speculation, Williams have finally confirmed their driver line-up for 2018 with Sergey Sirotkin signed as Lance Stroll’s new team-mate.

With Felipe Massa once again heading into retirement, Williams were in the hunt for a new driver for this year’s championship.

The team considered Robert Kubica, who was believed to be the favourite before a post-season test saw Sirotin emerge as the favourite as the 22-year-old Russian impressed in the Abu Dhabi outing.

“To say I’m happy and proud to join such a famous team like Williams is an understatement.  It took a huge amount of work to get where I am, and I’m really happy and thankful to everyone involved.
