The Williams Formula 1 team will reveal what it calls a "title partnership and livery launch" on Monday February 11th.
The event will take place at 3pm UK at the team's Grove factory.
Although this week the FIA revealed an official entry list that named it only as Williams Racing, the team said that it is revealing a title partner, with a spokesperson from the company concerned appearing alongside Claire Williams, Robert Kubica and George Russell.
A Williams social media post announcing the livery launch included a flash image of a car, but it was not clear whether it was the actual 2019 design.
The new livery will include Polish sponsorship associated with Kubica.
The title partnership slot is available after Martini's contract came to an end in 2018, and a planned deal with Rich Energy failed to materialise after the energy drink company made a last minute switch to Haas.
