A bstractIn this short note I show that the soft limit for colour-ordered tree-level YangMills amplitudes contains a sub-leading divergent term. This term is analogous to those found recently by Cachazo and Strominger for tree-level gravity amplitudes.

In fact such a subleading gluon relation was argue”
