When Cameron denies the people a voice over membership of the European Union purely because their wish is at variance with his own belief, he acts not as the head of a democracy.
In the words of Albert T. Bledsoe:
"If the right of secession be denied and the denial enforced by the sword of coercion; the nature of the polity is changed, and freedom is at its end. It is no longer a government by consent, but a government of force."And therein lies yet another reason for change in the system of democracy by which we live.
