Opposition politicians and leaders of parties seeking to oust the government launched sharp criticism at Israeli Prime Minister Benjamin Netanyahu and his closest advisers after a report by the newspaper Israel Hayom.

According to the publication, three of the prime minister’s advisers allegedly passed compromising information about Egypt to Qatar while receiving money from Doha.

As Israel Hayom reports, the leaks concerned secret information about a possible Egyptian violation of the peace agreement with Israel due to the deployment of additional forces to the Sinai Peninsula. Defense officials feared that the transfer of this data could jeopardize the peace treaty with Egypt and reduce Cairo’s willingness to help secure the release of hostages held by Hamas. Qatar, it is claimed, used the information it received to shape negative attitudes toward Egypt in Israel and strengthen its role in the negotiations.

“This is what treason against Israel looks like. Netanyahu’s advisers, who were receiving money from Qatar, endangered our strategic relations with Egypt for Qatar’s interests,” said Yair Golan, chairman of the Democrats party.

According to him, five wars and the deaths of thousands of Israeli servicemen led to the conclusion of the peace agreement with Egypt, yet Netanyahu’s office allegedly was not afraid to put it at risk for financial gain.

Yashar party chairman Gadi Eisenkot also criticized Netanyahu and called for the creation of a state commission of inquiry. According to him, “any reasonable prime minister” would have ordered an investigation to determine the circumstances of what happened and make sure that his staff were acting in Israel’s interests rather than those of another state.

Opposition leader Yair Lapid noted that the Likud party had previously blocked his proposed bill to designate Qatar as a hostile state. Lapid’s party ally in Be-Yachad, Naftali Bennett, for his part, used the publication to criticize Doha, calling Qatar a “poisonous enemy” and promising, if elected, to minimize its influence over the Gaza Strip.

Netanyahu’s advisers Yonatan Urich, Israel Einhorn, and Eli Feldstein are key suspects in the case known as “Qatargate.” The investigation is tied to suspicions that they committed a number of offenses, including contacts with a foreign agent and corrupt acts related to the alleged promotion of Qatar’s interests through lobbyists and businessmen while working in the circle of the Israeli prime minister.
