Marko, a motorsport advisor for Red Bull, caused a stir after the Italian Grand Prix when he blamed Sergio Perez’s fluctuating form on his ethnicity.
He told Red Bull’s own Servus TV channel: “We know that he has problems in qualifying, he has fluctuations in form. He is South American and he is just not as completely focused in his head as Max (Verstappen) is or as Sebastian (Vettel)."
As well as Mexico being in North America, Marko’s comments were criticised by many as being blatant racial stereotyping – which prompted him to issue an official apology.
But Hamilton, who has done much to campaign for less discrimination in F1, thinks that saying sorry is not enough and felt it "interesting" that no action has been taken against Marko when Red Bull has done so over others after similar incidents.
Asked by Sky if we surprised there had been no statement from senior figures within F1, Hamilton said: "I think this is not something that you just apologise [for] and it is all okay. I think there needs to be more done.
"I think teams, when they've had individuals, particularly drivers, make comments but [also] some individuals in the back room, they usually are removed or at least they put out a quote and say they don't support that sort of thing.
"So it is interesting they haven't done so for this one.
"But that's not my team. That's not how we move as a team. And I think it just shows how important is that we continue to do the work, the work that I'm trying to do with my team, and with the sport.
"We still have a lot of work to do moving forwards to make sure that this is a more inclusive environment.”
