Naomi Campbell shames Vogue for racial diversity

One of Enninful's first appointments was to hire Campbell, Kate Moss and film director Steve McQueen as contributing editors.

Speaking to Time last year, he said there needed to be widespread change to make the fashion industry more diverse.

"If you put one model in a show or in an ad campaign, that doesn't solve the problem," he said, according to BBC News.

"We need teachers in universities, we need internships, we need people of different ethnic backgrounds in all parts of the industry. That really is the solution; you have to change it from the inside."

In the same interview, Campbell said: "For me, it never stops. It's not a fight, it's a conversation - constantly reminding people that diversity is beautiful and that there should be diversity and equal opportunity.

"It never stops because you say it and they say that they listen, and it seems to take two steps backwards."
