Israeli media said Wednesday that Prime Minister Benjamin Netanyahu is close to agreeing a unity government with the main opposition leader.

The head of the rightwing Likud has reportedly been engaged in intense negotiations with Labour Party chief Isaac Herzog in recent weeks in a bid to form a unity government.

Herzog, whose party forms the Zionist Union along with the centrist Hatnuah, could present a possible coalition agreement to his party in the coming days, the reports said.

His entry into the government would be closely watched by the international community for its potential impact on the stalled peace process with the Palestinians.

An advocate of an independent Palestinian state, Herzog has been touted as a potential foreign minister -- a role currently assumed by Netanyahu in a temporary capacity on top of his role as premier.

Egyptian President Abdel Fattah al-Sisi on Tuesday urged Israelis and Palestinians to take historic steps to "achieve peace", comments which some analysts interpreted as an attempt to boost the idea of Herzog joining the government.

If a unity government is formed Netanyahu and Herzog could visit Egypt to launch a new peace initiative under the auspices of the Egyptian president, the Jerusalem Post cited anonymous officials from both parties as saying.

But resistance to the coalition is strong within both camps and commentators stressed an agreement was far from certain.

Herzog's main rival in the Labour Party, Shelly Yachimovich, described the possible alliance as a "blood wedding".

She promised on her Facebook page to fight for "justice, clean government, ideology, and the honor of the party".

Within Likud, several members said they would prefer an alliance with the nationalist party Israel Beiteinu rather than Labor.
