Ernest, you are trying to make political capital out of an accusation that really should have politics kept out of it.
For once in your life give it rest.
You tend to find on the far left that groups either are run like cults or are very flaky and split at the drop of a hat. From what I have seen on the right the equivalent groups tend to fragment quite a lot.
The closest I have got to the SWP is them selling newspapers outside a Labour party meeting I was at but they do display a lot of cult like behaviour an the woman might have been so into it she thought they could sort it out within the organisation.
That is largely speculation on my part though.
If anyone thinks this is restricted to one political party they are deluded. If anyone think this is restricted to Parliament they are even more deluded.
One official - who I hope is identified and got rid of if they are still in the party - attempted to brush it under the carpet, not the entire Labour Party.
