Using the O(a) Symanzik improved action an estimate is given for the strange quark mass for unquenched (n f = 2) QCD. The determination is via the axial Ward identity (AWI) and includes a non-perturbative evaluation of the renormalisation constant. Numerical results have been obtained at several lat
