Tim Pallas, roads minister for Victoria, the Australian state where yesterday's Grand Prix was held, branded Hamilton a "d***head" on live radio.
But Aussie hero Mark Webber said his home country's attitude to the incident had "p***ed" him off".
Pallas made the jibe at Hamilton as he was quizzed about a government-backed advertising campaign to educate young people about driver safety, in which
ads feature the slogan: "Don't be a d***head."
Asked about Hamilton's conduct, Pallas replied: "He's certainly a very
silly young man, quite frankly."
The show host persisted: "Come on, you're the one who's using the language. Is he a d***head?"
Pallas responded: "Well, yes OK, I'll say it. He's a d***head."
The minister also called Red Bull star Webber "irresponsible" after the driver said Australia had turned into a "nanny state".
Webber fumed: "It's certainly changed since I left here. It p***es me off coming back here, to be honest.
"It's a great country but we've got to be responsible for our actions. And it's certainly a bloody nanny state when it comes to what we can do."
Although indignant at Webber's blast, Pallas insisted he was not as big a villain as Hamilton.
He said: "I think what Mark Webber has done has been totally irresponsible. But he didn't display the behaviour that Lewis Hamilton did, and that was to put people's lives at risk."
