This paper investigates heat and mass transfer in a Magnetohydrodynamic flow over a moving vertical plate with convective boundary condition in the presence of thermal radiation. Similarity method is used to transform the system of coupled non-linear partial differential equations, governing the flow, heat and mass transfer problems to a system of coupled non-linear ordinary differential equations. The resulting equation is then solved, using Homotopy Analysis Method (HAM). The effect of thermal radiation, Magnetic Parameter and all other parameters encountered in the course of the investigation were examined on the fluid flow, heat and mass transfer. The results show among all other obtained that higher values of radiation parameter pioneer the dominance of conduction over radiation and consequently depressed the thermal boundary layer thickness.
