In this paper Yang-Mills theory in conformal (essentially nonlocal) gauge is considered. This gauge is expressed in a local form by means of two auxiliary scalar fields. By the use of the BRST symmetry, the Slavnov-Taylor identities are obtained. These identities are applied to prove the renormalizability of the theory as well as to investigate the structure of the radiative corrections to the two-point vertex functions. It is shown that here a class of conformal anomalies arises, connected with the absence of radiative corrections to the propagators including auxiliary fields.
