Party leader Jimmie Åkesson had urged Ekeroth on Thursday to step down temporarily and the party announced Friday evening that he would for the time being.
"Let us hope that this will be thoroughly investigated so that we can focus on politics again," Ekeroth was quoted as saying in a press release. "I agree with Jimmie Åkesson's assessment. Until further notice, I will not represent the Sweden Democrats in the Justice Committee."
A man reported Ekeroth to the police after he allegedly punched him in the face during an argument outside the downtown night club late Wednesday. According to newspaper Aftonbladet, the man said something to provoke Ekeroth after the Sweden Democrat MP was declined entry to the club.
Ekeroth himself, however, claims he acted in self defence.
In November 2012 Ekeroth was one of three leading Sweden Democrat politicians using racist and sexist jeers against several people, among them the comedian Soran Ismail, during a night out. In a video from the night, the three party members were seen picking up metal pipes and behaving in a threatening manner.
