I would not go quite that far, Dave. They did identify a few cases and said this was "the tip of the iceberg" - but most of the other 18(?) cases they looked at in detail were by people that the Labour Party did not have legal responsibility for, or it was unclear what capacity these people were speaking in. Having said that, they also stressed other parties had similar issues.

I put the question mark after the 18 because that figure was mentioned but there are other complaints and I would need to double check the status of these 18.

The cases that they referenced, though, were often to illustrate where the process had fallen short.
