Yishai's activists sparked a storm in the political arena by publicizing ads for Yishai on social media urging voters to vote for Yachad "in order that there shouldn't be a child with two fathers."
The two party leaders have been bitter enemies since Deri ousted Yishai as Shas chairman in 2013.
Former leader of Sephardic ultra-Orthodox party blasts cabinet decision to create egalitarian prayer space "an attack on the Holy of Holies."
"Deri is a wheeler-dealer, who must decide whether he represents the poor who he said were invisible poor or the gas tycoons," says former Shas chairman.
The prime minister meets with the former head of Shas amid reports of building right wing bloc ahead of next general elections.
Election leaves party with large debt, no party funding.
Eli Yishai may run in the J'lem mayoral election against Nir Barkat, given Uri Lupolianski announces that he’s not running.
Source close to former Shas chairman says haredi MK knows he would have trouble obtaining support from any of the religious factions.
Deri orders his followers not to rejoice upon his return to the Shas leadership, because Yishai would see it as gloating.
