After a short introduction to non-perturbative QCD contributions of CP-violation
in the standard model, the problem of lattice operator renormalisation is discussed.
Wilson fermions with a chirally twisted mass term are introduced, with emphasis on
their application to the computation of B_K and the Delta I = 1/2 rule. Some results
on B_K are presented.
