I dialled into the call. Was pretty much as expected - the LGEBC outlined what they do, what they take into account with boundaries. Then Jim Dickson and a council manager talked a bit about it from Lambeth's perspective, then Jim talked through the changes.
It was mildly odd, he didn't seem that against them. He spoke favourably here and there about aspects of the proposal and said he thought 2 councillor wards are probably better from an equalities perspective (he thinks it would be easier to get more women/ethnic minorities selected. He didn't explain why). He did however give what seemed to be a clear suggest to those opposed to write in about equalities. He talked a bit about the cross party group and how they were in general agreement but not on all recommendations. He didn't mention the Lib Dem's role, but then they were not part of that so I guess that makes sense.
Then there was a Q&A handled by Jim, the council staffer and the two LGEBC staffers. That was mildly interesting. Few people seemed interested in the naming questions - someone stuck up for Tulse Hill. More people were asking about 1 v 2 councillors v 3 for work load, or particular boundaries chosen. Someone was pretty anti the new Streatham Hill / Thornton boundaries. The one person ward in Streatham got raised in that context. There were some questions from Labour types - one asked if they would be prepared to make significant changes to the whole scheme (she's an ex councillor).
I didn't get the impression that there was a massive groundswell of opposition to the new boundaries or names. More just people annoyed about some of the choices and of course some Labour pushback.
The LGEBC did say repeatedly that they wanted especially for feedback or suggestions to explain both why the submitter doesn't like a specific proposal and what they would propose instead. THey also recommended people understand the kinds of thing the LGEBC are looking for - e.g what is the community, what are significant geographic features.
