"There are other reasons to be worried. One is the increasingly anti-parliamentarian rhetoric in which Benn engages. When he speaks about the primacy of the activists, he virtually parrots Lenin. He speaks a language which despises the ordinary party worker, again Lenin-like. The supremacy of party and activist is a central Leninist tenet, and Shirley believes she has read more Lenin and Marx than Benn has. She thinks he does not really know what he is saying. Also, that he is to some extent being used by people much harder than he is: Maynard-type, Richardson-type, Militant sympathisers."
