The legality of the Racing Point car is already being investigated as a result of the protest by Renault. According to Helmut Marko it just doesn't stay with one team.
Against F1-Insider, the advisor of Red Bull Racing announces that the protest will be extended. "According to the information we have, more teams will start protesting against Racing Point. We hope that there will be more clarity in the end". Interestingly, the Austrian just doesn't say that Red Bull Racing will also make a protest against the midfield team.
It will be an important statement for Red Bull Racing, because of its sister team. "If Racing Point's car is legal, we're just going to do the same with AlphaTauri's car," says Helmut Marko.
