Move comes after one of company’s biggest shareholders demanded information about allegations

The sportswear giant Adidas is to launch an independent investigation into allegations of misconduct made this week against the US rapper and fashion designer Kanye West, including that he showed pornography to staff at company meetings.
The claims by unidentified staff at Yeezy and Adidas, which surfaced in a Rolling Stone article on Tuesday, included allegations that the musician, who has changed his name to Ye, showed an intimate picture of his ex-wife, Kim Kardashian, in job interviews, and that his “problematic behavior” was overlooked by Adidas management.
