  Remarkable results have been published recently on the $\beta$ decay of
$^{56}$Zn. In particular, the rare and exotic $\beta$-delayed $\gamma$-proton
emission has been detected for the first time in the $fp$ shell. Here we focus
the discussion on this exotic decay mode and on the observed competition
between $\beta$-delayed protons and $\beta$-delayed $\gamma$ rays from the
Isobaric Analogue State.
