We present new results for the renormalisation and subtraction constants for the four fermion AF = 2 operators, computed non-perturbatively in the RI-MOM scheme (in the Landau gauge). From our preliminary analysis of the lattice data at p = 6.45, for the B" -B" mixing bag-parameter we obtain BEG' =
