Description: Soft theorems are the statements about the IR structure of quantum field theories. The soft graviton theorem relates the amplitudes with soft external gravitons to those without the soft gravitons. We prove the sub leading Multiple soft graviton theorem in an arbitrary theory of gravity. The results are valid to all loop orders when space-time dimension is greater than five and upto tree order otherwise due to the enhanced IR divergences of S matrix. We do not assume any other details of the theory except that it possesses general coordinate invariance.
