Labor MK Avishai Braverman urged Wednesday morning that his party leave the coalition following the the Israeli and US announcement that negotiations over the settlement freeze failed, Army Radio reported.
Tensions intensified Tuesday night within Labor after Barak prevented Braverman from speaking to the media.
Moments before Braverman went up to the podium during a Labor office meeting, Barak and and the party's secretary-general decided to block the entry of journalists, who were invited in advance, to the meeting.
Braverman told reporters after he left the office that "Voices won't be silenced within Labor!" and "This is a despicable act, which is another example that such leadership has no place here," reported Army Radio.
