An Israeli political party campaigning against pornography has launched its bid to enter the Knesset with a creepy video warning about the dangers of children's exposure to adult materials online.

Defending Our Children – No More Feeding Them Pornography is one of the political outsiders hoping to snatch a seat in the country's legislative elections next month.

Headed by Yehezkel Shtelzer, a 43-year-old ultra-orthodox, the party is running on an anti-porn ticket, advocating for stricter laws on X-rated content online, the Jerusalem Post reported.

"There are hundreds of thousands of porn addicts in this country," Shtelzer told the newspaper. "It is totally irrational for a nine-year-old boy to be exposed to pornography. If his parents want, they could buy him Internet access for his birthday, but the rest of the public should have filtered Internet."

This week, the party released on YouTube a campaign video titled: "Abandoning the place where our children dwell".

The 40-second clip shows a mother allowing into her family house what appears to be a group of far-right fanatics, and then an entire porn movie crew, including scantily dressed actresses.

"Hi, is Claus in here?" a pornstar asks, referring to the woman's son. "Yes, upstairs," she replies. "Well then, we'll go up and try some kinky stuff," the actress concludes.

Finally an actor seemingly impersonating a paedophile also rings the doorbell, asking for the woman's little daughter, Anna, who accompanies her mother at the door while holding a stuffed bunny in her arms.

"You got a nice, bunny; come on I'll show you a real bunny" the man tells her before leading her away.

The party already unsuccessfully attempted to enter parliament in 2006 and 2012.

Israelis are to vote on 17 March. According to a Knesset Channel poll released this week, PM Benjamin Netanyahu's Likud party and centre-left coalition Zionist Union are currently in a tie, as they are both expected to win 24 of the Knesset's 120 seats.

However, according to another survey by Haaretz newspaper, more than 20% of voters are still undecided.
