But beyond the impact of what could be a significant change at the top, the development has shone a spotlight on what now appears to be a war for control of the squad.
What originally started as the story of an isolated complaint by a female employee against the behaviour of Red Bull boss Christian Horner, has morphed into a fight that could well decide the fate of the F1 team itself.
With Marko almost certain to learn his future on Saturday, when he meets with Red Bull CEO Oliver Mintzlaff, any move to suspend him or hasten his retirement could well trigger the exit of Max Verstappen before his current contract expires. And where would all that leave Adrian Newey?
It is a situation that could lead to the whole house of cards tumbling down, as the key pillars that have helped turn Red Bull into a dominant force are potentially pulled away.
Where things go from here is hard to predict right now, but what is significant is how the latest drama surrounding Marko has exposed perhaps best what has really been going on behind the scenes.
It’s been clear since the Bahrain Grand Prix – when anonymous emails were sent to senior F1 personnel of alleged evidence at the heart of the Horner investigation – that there were dark forces at play here.
