Martin Strid has quit the Sweden Democrats (Sverigedemokraterna, SD) after saying that Muslims were "not completely human" during a conference.

Strid, a local politician from the town of Borlänge, told the audience at the party's national conference in Norrköping that there is a "scale of 1 to 100".

"On one end of the scale you are 100 percent human, a person, everything that’s part of that concept. At the other end, you are 100 percent Mohammedan," he said.

Strid continued by saying that "all Muslims are somewhere on that scale" and that members of terror group Isis "are close to being 100 percent Mohammedan".

"If you are an ex-Muslim you have come quite far towards being fully human," Strid continued.

He also said that he wanted to "free Muslims from Islam, the goal is for them to join SD instead".

The speech was recorded by broadcaster SVT, which also wrote on Sunday that Strid had been reported to police for hate speech.

SD party secretary Richard Jomshof called Strid’s statement "racist" and said he expects him to be excluded immediately, while Julia Kronlid, an MP with the party, called it "damaging".

"This is very bad, extremely bad. We had the chance to get our policies out [through the conference, ed.] and the only thing the media are writing about is this," Kronlid said.
