F1 drivers Jenson Button and Lewis Hamilton have condemned the booing of world champion Sebastian Vettel after he won the Singapore Grand Prix on Sunday.
According to the Guardian, Vettel's win on Sunday was his third straight victory for Red Bull and his third in as many races in Singapore.
Button said that he was quite surprised and was himself booed on the podium in Italy, because it was Ferrari's backyard, adding that it was a surprise in Singapore.
Hamilton said that no one should ever be booed or put down for their success.
Red Bull team principal, Christian Horner, also condemned the booing.
