The effect of horizontal magnetic field is considered on the stability of stratified viscoelastic Walters' (Model B') fluid in the presence of rotation. In contrast to the Newtonian fluids, the system is found to be unstable for small wavelength perturbations for the case of stable stratification. It is also found that the magnetic field stabilizes the certain wave-number band for unstable stratification in the presence of rotation and this wave - number range increases with the increase in magnetic field and decreases with the increase in kinematic visco-elasticity.
