The four “Labor Rebels” will hold their first activists' gathering on Sunday. The “rebels” - MKs Yuli Tamir, Ophir Pines-Paz, Amir Peretz, and Eitan Cabel – have expressed disappointment with the path their party has taken, and are openly seeking to form a breakaway party.

A fifth Labor MK, Daniel Ben-Simon, is rumored to be considering attending the gathering as well.
