*“Monopoles, Dirac Strings and Generalised Symmetries"*

_Abstract_
Dirac’s action for electrically and magnetically charged particles 
interacting with the electromagnetic field involves singular Dirac 
strings which introduce a form of non-locality in the formulation. These 
are invisible provided they do not intersect charged particle 
world-lines – this is known as the Dirac veto. It is shown that this 
system has 1-form generalised symmetries and the Dirac veto can be 
viewed as a restriction to configurations in which certain anomalies vanish.
