During the Austrian Grand Prix weekend, Verstappen Sr was due to take part in the Red Bull Legends Parade and drive the 2012 championship-winning RB8 around the Red Bull Ring.
And speaking on Sky Sports prior to qualifying, Brundle expressed his sympathy to the three-time champion as he gave his verdict on an ‘unnecessary’ situation.
"I can’t believe we’re having to talk about it but I think it is significant in a way,” he said. “Blood's thicker than water, Max will always support his dad and other key people that have been around him for a very long time.
"It just seems petulant and unnecessary, and I think it’s so unfair on Max actually, to make him have to answer questions like that when he’s trying to focus on two races this weekend.
"They’ve had so much success together – every point, every podium, every victory, every world championship Max has had is with Red Bull. The money they’ve collected, because the kid’s a genius in a racing car, he’s earned all of those and all of that money.
"Why did they have to spoil it with some sort of petulant stuff?"
