We present an analysis of non-leptonic B decays in the minimally flavour-violating MSSM with large tan β. We relate the Wilson coefficients of the relevant hadronic scalar operators to leptonic observables, showing that the present limits on the B s →μ + μ − and B +→τ + ν τ branching fractions exclude any visible effect in hadronic decays. We study the transverse helicity amplitudes of B→VV decays, which exhibit an enhanced sensitivity to the scalar operators, showing that even though an order one modification relative to the SM is not excluded in some of these amplitudes, they are too small to be detected at B factories.
