SINGAPORE (AP) — Formula 1 champion Max Verstappen gave only brief answers at a news conference on Saturday in an apparent protest against series governing body the FIA for punishing him for swearing.

Max Verstappen said Formula One should not air team radio if the sport was concerned about bad language after the head of the governing FIA compared drivers to foul-mouthed rappers.

Max Verstappen has been told to “accomplish some work of public interest” in an odd ruling by the stewards after swearing during Thursday’s FIA press conference in Singapore. The Red Bull driver, who leads this year’s world championship by 59 points to Lando Norris, has not won in seven races and struggled last week in Azerbaijan.
