• The high energy behaviour of a double discontinuity of the six-point amplitude is studied in the dual resonance model and in a hybrid Feynman diagram model. This discontinuity imposes, through unitarity, a bound on the intercept of the bare Pomeron singularity. It is shown that in both models the ordinary Regge trajectories which couple to two-body amplitudes decouple from the discontinuity. The origin of this decoupling is discussed. The asymptotic behaviour of the double discontinuity is controlled by sister trajectories in the dual resonance model, and by the genuine three particle Regge poles in a Feynman diagram model. Insofar as the intercepts of these trajectories are lower than those of the usual Regge poles there is no strong constraint on the Pomeron.
