The commuting diagonal-to-diagonal transfer matrices of the self-dual Potts and Ashkin-Teller models on the square lattice are shown to satisfy special functional equations called inversion identities. These identities generalise the known local inversion or unitarity relations for interaction-round-a-face or IRF models satisfying Yang-Baxter or star-triangle equations.
