Max Verstappen has said that his father is 'very outspoken', after comments made by the 52-year-old about Red Bull team principal Christian Horner's future.
Horner has recently been the subject of an internal investigation into accusations of alleged 'inappropriate behaviour', an investigation which cleared him of any wrongdoing.
The 50-year-old vehemently denies the claims, and has said that he is 'pleased' that the process surrounding his conduct is over.
Who does F1 champion Verstappen back in Red Bull saga?
However, Verstappen senior's comments, and calls from rival F1 bosses for there to be an external investigation into the allegations, have brought the spotlight back onto Horner.
What's more, supposed 'leaked' messages allegedly sent by Horner were released during the Bahrain GP weekend, although they have not been confirmed to be in relation to the allegations.
