Stake F1 have been hit by a major stumbling block ahead of the 2024 F1 season, after Swiss authorities opened an investigation over Sauber's main sponsor backers.
Having ran under the Alfa Romeo moniker up until the end of last season, Sauber will enter 2024 as Stake F1, sponsored by a crypto casino operator.
However, the nature of the advertising has raised concerns among the Swiss authorities, who have opened an investigation into the sponsor's legal compliance within the national laws.
As a precautionary measure, Sauber have taken down the Stake logo from their website while the investigation is ongoing, and remain confident that the team's practices are in compliance with respecting national laws around the world over the sponsorship.
A Sauber spokesperson told GPFans: "Sauber Motorsport AG have always complied and continue to comply with all existing regulations, both Swiss and of whichever country we race in.
"The report of an ongoing investigation by the Swiss Authorities does not concern us: this is a procedure that will highlight our compliance with all applicable regulations."
