  In this paper, we shall consider an infinite-derivative theory of gravity,
with a view to making it renormalisable. First, we derive the modified
superficial degree of divergence. Next, we establish that the theory is
invariant under BRS (Becchi-Rouet-Stora) transformations. Consequently, we show
that the corresponding Slavnov identities hold for the theory. Finally, we
summarise our results and discuss renormalisability.
