unrepresentative

First of all, why do men vaguely feel that the House of Commons is unrepresentative?

Our so-called representative system is unrepresentative in a deeper way than the reformers who talk about the money power imagine.

I declare my belief that we are suffering, not from a too extended ballot, but from one too limited and unrepresentative.

As a deliberative body, convocation has done much useful work, but it suffers considerably from its unrepresentative nature.
