Kadima chairman Shaul Mofaz on Tuesday had a simple and dismissive message for Tzipi Livni and other former politicians who are attempting to siphon away MKs from Kadima: "Good luck."Addressing any Kadima MKs considering leaving the party, he said, "If there are people who want to leave, if they think [Kadima] should have a different agenda, then they should leave." The party has enough good members and plenty of good people who want to join Kadima, Mofaz told Army Radio.Asked whether it was the right move to join the government for only 70 days, the Kadima chairman blamed Prime Minister Binyamin Netanyahu, saying he failed to follow through on agreements reached between the two.Kadima entered the government in order to advance four issues, he said, universal service, a change in the system of government, negotiations with the Palestinians, and passing a responsible social budget in 2013. "The first test was the Tal Law."Netanyahu broke the coalition agreement with Kadima, Mofaz charged, by dismissing the Plesner Committee and its recommendations for replacing the Tal Law."Our exit [from the government] was unavoidable," he added.
