Lewis Hamilton has again accused Formula One of lacking diversity ahead of the opening race of the new season.
The British driver, 33, 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 story 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 the social media platform.
