Lewis Hamilton discusses his fight for more diversity in sport

Hamilton, who made his F1 debut in 2007, recalled looking around the Australian Grand Prix paddock in Melbourne at the start of last year and posting images on Instagram of the startling lack of diversity on display.

"And then I got to the end of the year and I saw all the photos of all the teams...and there were three or four people of colour within that setting and I remember thinking 'how has that not changed at all since I've been here?"

Hamilton also said the sport had gone a long way to breaking down barriers and opening up a dialogue.
