It was thanks to their hard work (to which I contributed, a bit) and that of Piers Corbyn's independent lot, that the Aylesbury Estate over in Southwark voted no to a stock transfer about 4 or 5 (?) years ago.
More recently superseded by a wholesale demolition/replacement plan for that estate. Southwark and various private consortia now have a big 'regeneration plan' for that estate, one of the biggest in Europe -- involving lots of profitable private housing on the sunnier side of the buildings, overlooking Burgess Park. The social element of the new housing will after all, despite the old ballot, be under a HA/Almo or something -- but legally a stock transfer ballot was not required for the new developments.
I think, and quite rightly so.
