Showrunner Mark Schwahn has been suspended from his E! drama "The Royals" amid allegations of sexual misconduct.

"E!, Universal Cable Productions and Lionsgate Television take sexual harassment allegations very seriously, investigate them thoroughly and independently, and take appropriate action," said the studios in a statement to variety.com.

"Lionsgate has suspended Mark Schwahn from ‘The Royals' as we continue our investigation."

Created by Schwahn, "The Royals" wrapped up production on its fourth season in September and is set to premiere in March.

In a letter to Variety, 18 women who worked on Schwahn's previous show, "One Tree Hill", came forward to accuse Schwahn of sexual harassment.

"The Royals" is produced by Lionsgate Television and Universal Cable Productions. The show tells the story of a fictionalised version of the British royal family.

Its actress Alexandra Park has also issued a statement indicating that she experienced harassment and misconduct from Schwahn similar to that being alleged by the team of "One Tree Hill".

"I have a responsibility as someone who was working under Mark Schwahn on ‘The Royals' to acknowledge these claims," Park said in a statement posted on Twitter on Wednesday.

"I am devastated to admit to myself, to my colleagues, and to this industry that I too, have been exposed to this reprehensible behaviour."
