Sky Sports F1 pundit Craig Slater has said that Christian Horner, Helmut Marko and Max Verstappen all sat down for lunch together during pre-season testing, despite reports of 'friction'.
The 50-year-old is remaining in his position as Red Bull team principal while the investigation is ongoing, and was able to provide an update on his situation during pre-season testing in Bahrain.
"I was interested to note that Max had lunch with Christian Horner today, who is still doing his job as team principal and chief executive of Red Bull Racing," Slater told Sky Sports.
"Another party at that lunch was Helmut Marko. We have been aware of differences between the Verstappens, particularly Jos Verstappen and Christian Horner.
"There is also talk about friction between Horner and Helmut Marko, who Max is close to. Did the lunch today suggest that maybe those parties have settled those differences?"
