I shall begin with discussion of locality for integrable field theory in the form factor approach. Then I shall present a candidate for integrable irrelevant perturbation of sine-Gordon model proving the factorizability of scattering in the first order of perturbation theory. I shall discuss the S-matrix and locality for the perturbed model.
