McLaren have rejected suggestions Canadian billionaire businessman Lawrence Stroll is poised to take up a shareholding in the Formula One team.
Fashion magnate Stroll has recently been linked with investment in Sauber and Marussia as he eyes a position in the sport.
A report in Italy this week has claimed Stroll is ready to become a shareholder in McLaren, with Mansour Ojjeh, part owner of the TAG group of companies, looking to exit.
But a McLaren spokesperson said: "McLaren Group has not received any notification from any of its shareholders in respect of a wish to sell any shares in the company.
"In order to be able to sell shares in the company, they must first be offered to the other shareholders.
"These rumours are therefore without a foundation."

Elsewhere, the path was cleared for Thailand to host a Formula One Grand Prix in the future when a round of the Japanese Super GT series opened the country's first FIA Grade One circuit in Buriram at the weekend.
Plans for Thailand to host a Formula One race in 2015 foundered last year when a law was introduced banning racing in the historic area of Bangkok, scuppering the projected night race on the streets of the capital.
Thai authorities had reached an agreement in principle with Formula One's commercial rights holder Bernie Ecclestone in 2012 and the opening of the Chang International Circuit at the weekend means they now have a race-hosting facility.
More than 130,000 fans descended on the Hermann Tilke-designed track some 400km northeast of Bangkok for three days of racing and organisers said work would soon be undertaken to make it suitable for top class motorcycle racing.
