„This Party needs to protect itself against the activities of small groups of inflexible political persuasion, extreme so-called left and in a few cases extreme so-called moderates, having in common only their arrogant dogmatism. These groups, equally the multichromatic coalitionist fringe or groups specifically formed to fight other marauding groups, these groups are not what this Party is about. Infestation of this kind thrives only, and can thrive only, in minuscule local parties.“
— Harold Wilson
