We show that the position operator with commuting components proposed by M. Hawton [M. Hawton, Phys. Rev. A { \bf 59}, 954 (1999)] and developed in subsequent papers, including the recent ones, does not have the properties required for a photon position operator. Depending on the exact interpretation of the results it either concerns a triplet of massless spin zero particles rather than the photon, or does not have the required covariance properties under space rotations.
