Description: I will review the state of our understanding concerning the factorisation of soft and collinear divergences in multi-particle gauge theory amplitudes, to all orders in perturbation theory. I will then briefly describe two recent developments: a partial generalisation of the formalism to next-to-leading power in the soft approximation, and an application to the problem of infrared subtraction at NNLO and beyond.
