The Socialist Equality Party stands in Thursday's elections "on a history of struggle", a candidate said.
Chris Marsden said his was a Trotskyist party, as he spoke of "savage attacks made on jobs, wages and social conditions at the behest of the EU."
And he told Giles Dilnot on the Daily Politics his was a revolutionary socialist party, but others on the left were "like a ginger group on the Labour Party".
