In a dramatic development to the saga surrounding Red Bull team principal Christian Horner, it has emerged that Marko may face disciplinary action as the result of a fresh investigation that has been launched against him.
Just 24 hours after the female employee at the centre of the allegations made against Horner was suspended as a consequence of the findings of the probe into the matter, Marko is now under the spotlight.
Autosport has learned that Marko is subject to an investigation by Red Bull relating to various media leaks that have taken place since it emerged that Horner was being looked at by Red Bull's energy drinks company.
The investigation remains ongoing, and no conclusion has been reached regarding whether or not Marko breached team protocol at all.
However, if he is found guilty of having released confidential information to the media then he could face disciplinary action.
Marko confessed to Austrian broadcaster ORF in Saudi Arabia that there was a chance he could be absent from the next race in Australia.
Red Bull declined to comment on the matter when approached by Autosport.
