Williams will announce their 2017 driver line-up at their Grove headquarters on November 3, with Lance Stroll expected to be confirmed.
The Canadian teenager will turn 18 this weekend putting to an end any concerns about his age given that Williams’ title sponsor is Martini.
Stroll will step up into Formula 1 having won the 2016 European Formula 3 Championship with Prema Powerteam.
He will partner Valtteri Bottas, who is expected to remain with Williams despite months of rumours linking to a Renault race-seat.
Williams will make the announcement next Thursday, November 3.
