  A deep connection has been recently established between soft theorems and
symmetries at null infinity in gravity and gauge theories, recasting the former
as Ward identities of the latter. In particular, different orders (in the
frequency of the soft particle) in the soft theorems are believed to be
controlled by different asymptotic symmetries. In this paper we argue that this
needs not be the case by focusing on the soft photon theorem. We argue that the
sub-leading soft factor follows from the same symmetry responsible for the
leading one, namely certain residual (large) gauge transformations of the gauge
theory. In particular, expanding the associated charge in inverse powers of the
radial coordinate, the (sub-)leading charge yields the (sub-)leading soft
factor.
