Shelly Yechimovich and Yair Lapid accused Tzipi Livni on Monday of misrepresenting the conclusions reached in a meeting between the three politicians.
"Unlike what was agreed upon before and after last night's meeting, Tzipi Livni chose to present a false version of what had transpired during the gathering," Yechimovich and Lapid said in a joint statement.
"We convened out of mutual respect, even though we have many disagreements over ideology. We were shocked to learn that we were nothing but a backdrop for (Livni's) calculated spin, which didn't contain the faintest hint of truth. It has become evident that the invitation to meet was a trick though up by Livni, who is desperate."
Hatnu'a party head Tzipi Livni issued ab immediate statement denouncing "the unfortunate and unnecessary reaction" by the Labor and Yesh Atid parties.
According to Livni, this "proves that [Labor head Shelly Yecimovich and Yesh Atid head Yair Lapid] coordinated their positions before the meeting, during the meeting and after the meeting, in order to prevent the truth from surfacing - that they are self-serving and thus refuse to form a cohesive unit that can provide hope to the public."
"Their self-interest," Livni continued "precludes them from continuing discussions, but instead leads them to engage in spins and mudslinging. It is time the public learns the truth about their personal motives."
