The head of the Arab Joint List, Ayman Odeh, refused to hold any dialogue between the head of the "White-Blue" party, Benny Gantz, in charge of forming the government, and the Arab parties individually, according to Haaretz.
The joint list is a political alliance of four Arab parties in Israel: the Democratic Front for Peace and Equality, the National Democratic Alliance, the United Arab List, and the Arab Movement for Change.
The list was the third in the last Knesset elections last September, with 13 seats out of 120.
Gantz made three phone calls to leaders of the components of the joint list, with the exception of Knesset Speaker MK Muthanas Shehadeh.
Odeh, who is also the head of the Democratic Front for Peace and Equality, was quoted by Haaretz as saying that the joint list would engage in any dialogue as a bloc and would not allow Gantz to break it up.
He added that if Gantz wanted to address the joint list, he could communicate with him, but since he chose to contact the leaders of the parties that make up the list, he could not ignore one of them, he said.
He revealed that the joint list, if entered into negotiations with Gantz on the formation of the government, will demand the abolition of the law "Chemnitz", which provides for the establishment of mechanisms to accelerate the destruction of thousands of Arab homes in Israel under the pretext of the so-called non-licensing and raise the value of fines on their owners.
Odeh said the joint list would also demand the abolition of the Nationality Law, which states that Israel is the national home of the Jewish people, encourages settlement in the West Bank, restricts the right of self-determination in Israel to Jews, and considers Greater and Single Jerusalem as Israel's capital.
He added that his alliance would also demand that Gantz change the Israeli government's political approach to the peace process with the Palestinians, as well as strengthen the fight against Palestinian crime in Israel.
In a statement to the Anatolia news agency, President of the National Democratic Rally Mutans Shehadeh said that Gantz tried to break up the list by communicating with some of its vehicles.
Shehadeh stressed that the list "does not derive its legitimacy from Gantz originally, it is not the source of legitimacy, but our people," referring to the Palestinians inside, who represent about 21% of the population of Israel.
He added that the Israeli prime minister-designate should treat the joint list as one.
Shehadeh said Gantz sought to use the joint list as a tool to intimidate the Israeli right from the possibility of forming an Arab-backed government, to pressure Likud to enter a unity government with his "blue-white" alliance.
Israeli President Reuven Rivlin on Wednesday commissioned Gantz to form a government after outgoing Prime Minister Benjamin Netanyahu failed to form it.
Israel faces a political crisis after two inconclusive election rounds that give the winning Israeli parties a sufficient majority in the Knesset to form a government.
