Mustafa has been at the centre of controversy this week after being elected to the Social Democrats ruling organ last weekend. As leader of the Islamic Association he has taken part in meetings featuring speakers who have previously been known for having anti-semitic and homophobic views. Some in the party are now calling for him to distance himself more from their opinions.
Omar Mustafa himself has said he does not share their views, but party leader Stefan Löfven now says that he cannot be a member of the party board if he does not stand up for equal rights and gender equality.
He adds, however, that it is up to Mustafa's local Stockholm district to decide on his fate.
He told the Expressen newspaper: "The information I have been given shows that the Islamic Association does not have the same views as us when it comes to how we see women, and on equal rights between men and women", Löfven said, adding: "If you are to have a position of power in our party you need to stand up for our values to 100%, there cannot be an ounce of doubt".
