It emerged in Saudi Arabia on Friday that Marko is at risk of being suspended by the energy drinks company amid a fresh investigation into recent leaks to the media.
It is understood that the Austrian Red Bull company is looking into how information relating to the confidential investigation into team principal Christian Horner's behaviour was released to journalists during what was supposed to be a total media blackout throughout the company.
While Marko remains employed by Red Bull and is in Saudi Arabia, he told Austrian broadcaster ORF that there was a chance he could be suspended from Monday and be absent from this month's Australian Grand Prix.
Asked if he could face suspension, Marko said: "The theoretical possibility always exists."
But with developments in the ongoing Horner saga appearing to be far from over, now Red Bull driver Verstappen has escalated things further by indicating he will not accept Marko being out of the team.
It had been widely speculated in recent days that Verstappen's contract has a clause that would allow him to become a free agent if Marko left, and he has now revealed that he has told the team his future at the squad rests on what happens.
Speaking after grabbing pole position at the Jeddah circuit about whether Marko's fate could impact his own future, Verstappen said: "I have a lot of respect for Helmut and what we have achieved together.
