I'm referring to this post:

Unique minimal normal subgroup $\implies$ faithful irreducible representation.

Isn't the claim, that there is always a faithful irreducible representation (if $char(K) \nmid |G|$) trivial, because the trivial representation is always irreducible and faithful? So there whould be no need to look first, if there is an unique minimal normal subgroup.

The trivial representation is not faithful unless $G$ is trivial. –  Clive Newstead Aug 2 '12 at 10:45
    
Oh, of course, everything goes to 1! –  Khanna Aug 2 '12 at 10:50
