  We present a determination of the strange quark mass for two flavours (nf=2)
of light dynamical quarks using the axial Ward identity. The calculations are
performed on the lattice using O(a) improved Wilson fermions and include a
fully non-perturbative determination of the renormalisation constant. In the
continuum limit we find in the MSbar scheme at 2GeV, ms = 111(6)(4)(6)MeV using
the force scale r0 = 0.467fm, where the first error is statistical, the second
and third are systematic due to the fit and scale uncertainties respectively.
Results are also presented for the light quark mass and the chiral condensate.
The corresponding results are also given for r0=0.5fm.
