FIA president Mohammed Ben Sulayem said the grid’s stars had a responsibility to stop swearing on the radio and that they should not act like rappers.

Red Bull's three-time world champion Max Verstappen was punished for his language in a news conference at the Singapore Grand Prix in September.

The open letter by the Grand Prix Drivers' Association has also called on the FIA president Mohammed Ben Sulayem to 'consider his own tone and language' when talking about F1 drivers.
