Marko has caused a stir coming into this weekend’s Singapore Grand Prix after he blamed Sergio Perez’s inconsistent form this season on his ethnicity.
Perez said he had received a direct apology from the 80-year-old Austrian, who also issued a statement apologising for his “offensive remarks”.
“First of all, why would you be derogatory about one of your own drivers in a team that costs hundreds of millions a year to run?” Brundle asked.
“It seems a little bit odd to say the least. It’s completely unacceptable to broad-brush in a negative way people, continents, regions, countries in that way.”
Red Bull and F1 are yet to comment on the matter, something that has surprised Sky pundit Karun Chandhok.
“It’s a little bit confusing,” the ex-F1 driver added.
“As Lewis has suggested. when you have senior figures in a team that are clearly offensive, it’s quite surprising not to hear anything from the team itself or F1.
“It sounds like he’s had a one-to-one conversation with Helmut but he’s in a slightly different position because he’s employed by Helmut.
“Ultimately, as a sport we have to take a stand and there have been various moments in the last few years where the sport has come together and collectively taken a stand together.”
