The Knesset on Wednesday approved a bill prohibiting the publication of polls during the four days prior to any primary election. The bill constitutes a fine of NIS 67,300 (about $17,700).
The bill also states that polls that are published will be obligated to include certain details such as number of people polled, their background, and information regarding the method used to gather the data.
It was submitted a few months ago, and legislative procedure was spurred after Kadima Chairwoman Tzipi Livni's victory over her opponent, Transportation Minister Shaul Mofaz.
The polls on the Kadima primaries showed a landslide victory for Livni, but on election eve she won by just a small margin.
The new law is scheduled to take effect during the next few days, thus it will affect the primaries held by the different parties in preparation for the nationwide vote in February.
