The Morning Star has an interview with Nancy Platts, one of Labour's Brighton candidates. She says:
"The links have been weakened, but Labour remains a route into government for
the union movement."
A great message. "Standing up for special interests!" etc. Imagine what people would say if a Tory candidate said:
"The Tories are the main route into government for big business."
It would be seen as sinister, to say the least.
