Hamilton says 'nothing has changed' on diversity in Formula One

Lewis Hamilton has taken aim at Formula One after he accused the sport of lacking diversity ahead of the opening race of the new season.

Hamilton, the 33-year-old British driver, had appeared alongside his rival Sebastian Vettel at the sport's official press conference to answer questions on his championship defence.

But moments after he left the press conference room at Albert Park in Melbourne, Hamilton posted a video to his Instagram account in which he suggested F1 should do more to encourage participation from a wider range of ethnic backgrounds.

Four-time champion Hamilton is the sport's first and only black driver and has six million followers on Instagram.

Hamilton recorded the 15-second video from his Mercedes team's hospitality suite of a number of people in the paddock, and accompanied the clip with the words: "There's barely any diversity in F1.

"Still nothing's changed in 11 years I've been here.

"Kids, people, there's so many jobs in this sport of which anybody, no matter your ethnicity or background, can make it and fit in."

He ended the post with two hashtags, 'diversity', and 'you can do it'.

Formula One elected not to comment on Hamilton's remarks when contacted by Press Association Sport.
