  A fresh analysis of Left right symmetric supersymmetric models in the generic
case where the scale of right handed symmetry breaking $M_R >> M_{SUSY}\sim
M_W$ is presented. We conclude that the low energy effective theory for such
models is essentially the MSSM with R parity (and therefore B,L symmetry) but
the spectrum includes heavy conjugate neutrino supermultiplets that permit a
seesaw mechanism and several characteristic charged supermultiplets over and
above those of the MSSM.
