A Likud MK is pushign legislation to hold Prime MInister Benjamin Netanyhau to a campaign pledge to annex parts of the West Bank.
Sharren Haskel was to set propose a bill on Monday that would calls for the eastern side of the Jordan Valley to be brought under full Israeli sovereignty.
Several days before the election campaigns officially kicked off, Netanyahu called a press conference at which he stated that when re-elected, he would work to implement full sovereignty over the Jordan Valley, citing security concerns.
Blue and White officials scoffed at the statement, saying: "The citizens of the Jordan Valley are not props for Netanyahu's propaganda."
The party added: "Blue and White already stated that the Jordan Valley is eternal part of Israel. Netanyahu was the person behind a plan to hand over the territory (to the Palestinians) back in 2014."
Haskel's bill proposal would permit Palestinian residents in the territory to apply for Israeli citizenship within ten years of its implementation, provided they were not charged in the past with any security offenses and have not publicly called for a boycott against Israel.
"It's time to make the residents of the Jordan Valley legal Israeli citizens, thus kick-starting the development and prosperity of the region," said Haskel on Sunday.
"The communities of the Jordan Valley and their residents are a strategic resource of the highest order for Israel," she said.
"There is a wide consensus today about the region, following the long-awaited U.S. president's recognition of the Golan Heights as under Israeli sovereignty. It is time to do the same with the Jordan Valley.
"After Blue and White leader Benny Gantz proposed to do the same, I call upon him and my fellow party members to support my proposal."
New Right MK Ayelet Shaked proposed a similar bill Sunday, regarding the Gush Etzion bloc of settlements and Ma'ale Adumim settlement in the West Bank.
"We have in our hands a diplomatic window of opportunity and the support of the U.S. for such an action, an opportunity that will not last for long. We must not hesitate or delay," said Shaked on Sunday.
