The shareholders are keen to protect their investment in the brand, and that includes saving the relationship with Haas.

One source told Motorsport.com: “The deal is not terminated and William has no authority to do so. The investors are trying to clear up the PR mess, but it’s business as usual.”

The shareholders listed alongside Storey for Rich Energy UK are Brandsellers Holdings Ltd, Robert Lee, Charlie Simpson, Neville Weston and Lloyd Tunicliffe.

It’s believed that the same investors are also involved in a separate holding company which is in effect where the power lies.

Former Sainsbury’s boss Justin King, appointed as advisor to Storey and Rich’s board of directors in April, is believed to be involved in sorting out the situation.

King’s son Jordan, an IndyCar and F2 racer, had announced a sponsorship tie-in with Rich back in April.

On Thursday, Haas issued a statement quoting team boss Gunther Steiner as saying: “Rich Energy is currently the title partner of Haas F1 Team. I cannot comment further on the contractual relationship between our two parties due to commercial confidentiality.”
