MK Tzipi Livni (Zionist Union) made clear on Saturday night that she against her party joining a unity government headed by Binyamin Netanyahu.

“I object to joining this government,” she wrote in a letter to party members. “We have nothing in common with the government, and those who are members of it are partners to the erosion of our values.”

Livni added that recent attacks by members of the coalition against Defense Minister Moshe Ya’alon after he condemned the soldier who shot a terrorist in Hevron, as well as attacks against the Supreme Court, stress the importance of the Zionist Union remaining in the opposition.

“These recent difficult weeks, in which in addition to the terrorist attacks we saw attacks on the values ​​of the IDF, the Defense Minister and the Supreme Court, emphasize the importance and necessity of a fighting opposition these days,” she wrote, adding that “we need to stand firm and fight for our values.”

Livni’s letter comes after Finance Minister Moshe Kahlon said at a conference in Eilat this week that talks took place between the Likud and the Zionist Union regarding joining the opposition.

“There were contacts with Herzog to enter the government, and [the police probe against Herzog] pushed them aside,” said Kahlon, who added, “The only party I believe has the potential to join the government is the Labor party, but [the probe] made it less likely.”

Meanwhile, Internal Security Minister Gilad Erdan (Likud) warned on Thursday that the government is at risk of collapsing if Netanyahu’s narrow coalition of 61 MKs – the smallest majority possible – is not enlarged soon.

“The government will not be able to last much longer,” Erdan, a senior Likud member, told Army Radio.

“I hope that Zionist Union or another party will show responsibility and join the government, we don’t need to go to elections,” he added, warning warned that a unity government was necessary in order to pass the budget and advance the goals of the government.
