The hydromagnetic mixed convective fluid flow over a continuously moving inclined plate embedded on a porous medium under the influence of constant applied magnetic field with Ohmic heating has been investigated. The periodic transverse suction velocity is applied to the surface due to which the flow becomes unsteady. The visco-elastic fluid flow is characterized by Walters liquid (Model B¢). Approximate solution of the problem is obtained by using multi-parameter perturbation technique. The analytical expressions for velocity, temperature and concentration fields at the surface have  been obtained and illustrated graphically. The effects of visco-elastic parameter in combination with other flow parameters are prominent at all points of the fluid flow region for both Newtonian and non-Newtonian cases. Again, the concentration field is significantly affected in case of Newtonian fluid but not affected by visco-elastic parameter.
