An algebra is \emph{congruence regular} if each congruence relation of the algebra is

\theta =\psi$.

A class of algebras is \emph{congruence regular} if each of its members is congruence regular. 

Congruence regularity holds for many 'classical' varieties such as groups, rings and vector spaces. 

This property can be characterized by a Mal'cev condition ...
