Tens of thousands of Israelis have taken to the streets to protest after Benjamin Netanyahu fired his defence minister over his opposition to a planned judicial overhaul. Yoav Gallant had called on the prime minister to scrap the proposals which have divided the country, led to mass protests and sparked growing discontent within the military. Netanyahu’s move on Sunday underscored his determination to press on with the overhaul which has also angered business leaders and raised concerns among Israel’s allies. Gallant was the first senior member of the ruling Likud party to speak out against the plan. But as droves of protesters flooded the streets late into the night, other Likud ministers began indicating willingness to hit the brakes. Culture minister Micky Zohar, a Netanyahu confidant, said the party would support him if he decided to pause the judicial overhaul. A parliamentary vote this week will take place on a centrepiece of the overhaul – a law that would give the governing coalition the final say over all judicial appointments. It also seeks to pass laws that would grant parliament the authority to override supreme court decisions and limit judicial review of laws. In a brief statement on Sunday, Netanyahu’s office said the prime minister had dismissed Gallant. The decision came less than a day after Gallant called for a pause in the controversial legislation until after next month’s Independence Day holidays, citing the turmoil in the military over the plan. Gallant tweeted shortly after the announcement that “the security of the state of Israel always was and will always remain my life mission”. There was immediate outcry over his sacking with tens of thousands of Israelis taking to the streets to protest on Sunday evening with reports that demonstrators had breached barriers close to Netanyahu’s home in Jerusalem. Demonstrators blocked Tel Aviv’s main artery, transforming the Ayalon highway into a sea of blue-and-white Israeli flags and lighting a large bonfire in the middle of the road. Protests took place in Beersheba, Haifa and Jerusalem, where thousands of people gathered outside Netanyahu’s private residence. Police scuffled with demonstrators and sprayed the crowd with a water cannon. Thousands then marched from the residence to the Knesset, Israel’s parliament. Israel’s consul-general in New York said he was resigning in protest at Netanyahu’s treatment of his defence minister. “I can no longer continue representing this government,” Asaf Zamir said on Twitter. “I believe it is my duty to ensure that Israel remains a beacon of democracy and freedom in the world.” Yair Lapid, the opposition leader, said Gallant’s dismissal was a “new low for the anti-Zionist government that harms national security and ignores warnings of all defence officials”. “The prime minister of Israel is a threat to the security of the state of Israel,” Lapid wrote on Twitter. Avi Dichter, a former chief of the Shin Bet security agency, is expected to replace Gallant. Dichter had reportedly considered joining the defence minister but instead announced on Sunday that he was backing the prime minister. Netanyahu and his allies say their plan will restore a balance between the judicial and executive branches and rein in what they see as an interventionist supreme court with liberal sympathies. But critics say the laws will remove the checks and balances in Israel’s democratic system and concentrate power in the hands of the governing coalition.
