  The emission of W and Z gauge boson is included in a traditional QCD + QED
shower. The unitarity of the shower algorithm links the real radiation of the
weak gauge bosons to the negative weak virtual corrections. The shower
evolution process leads to a competition between QCD, QED and weak radiation,
and allows for W and Z boson production inside jets. Various effects on LHC
physics are studied, both at low and high transverse momenta, and effects at
higher-energy hadron colliders are outlined.
