Aurura, you are right about the split in the CWI and the IMT, but it is my understanding that the CWI still upholds Grant's theory of entryism, even if they differ, and split, over its implementation. The cause for the split was that they disagree that parties like British Labour are still parties of the working class, which Grant's IMT continues to argue. They still agree, in principle, with the idea of deep entryism into "labor parties," however those might be defined. At least that's my understanding.
