review text: The authors give a necessary and sufficient condition for a marginal extension to be irreducible and primitive with respect to a given variety \(\mathcal V\). It is also shown the existence of \(\mathcal V\)-marginal irreducible extensions and of a \(\mathcal V\)-covering group of a given \(\mathcal V\)-perfect group.
