%X Rare B decays provides an opportunity to probe for new physics beyond the standard model. the effective Hamiltonian for the decay $b \to s l^+ l^-$ predicts the characteristic polarization for the final state lepton. Lepton polarization has, in addition to a longitudinal component $P_L$, two orthogonal components $P_T$ and $P_N$ lying in and perpendicular to the decay plane. In this article we perform a study of the $\tau$-polarisation asymmetry in the case of SUSY models with large $\tan\beta$ in the inclusive decay $B \to X_s \tau^+ \tau^-$.
