Four years ago the Federation broke ranks to launch a separate initiative, its “mehadrin” meat brand, widely seen as a move to compete against Kedassia in the expanding strictly Orthodox market.
Although the Board initially condemned the manoeuvre, unity held and the three-way alliance continued.
It would not, however, be the first time the Federation has decided to go it alone.
It went independent in the 1980s but not long after it returned to the Board, the United Synagogue quit to start its own meat venture.
Unity was eventually restored in 1993.
