Abstract: We complete the classification of edge-symmetric distance-regular coverings of complete graphs with $r\not\in\{2,k,(k-1)/\mu\}$ for the case of the almost simple action of an automorphism group of a graph on a set of its antipodal classes; here $r$ is the order of an antipodal class.

Keywords: edge-symmetric graph, distance-regular graph, complete graph, covering, antipodal class.
