N2 - We calculate the proton decay rate for the mode p→K+v̄μ in the minimal SU(3)×SU(2)×U(1) supergravity model, with flavour diagonal squark-quark-gluino couplings dressing d=5 operators. It is shown that, for reasonable ranges of parameters, the decay rate may be close to the present limits. This possibly requires that the VEVs of the Higgs doublets be similar. Comparison with flavour changing couplings indicates that the diagonal case will be dominant, except if the third generation mixing angles are close to their upper bounds.
