Just had a catch-up read of the last ten days or so. Seems like now would be the time to pile on the pressure - it will suit NR fine if they have the initiative, and once they submit a planning application it becomes a semi-judicial process - even if Lambeth turn it down because it makes political sense for them, NR have a free appeal to the National Planning Inspectorate who are not allowed to consider local politics - only legalistic planning issues - and it is unlikely that there will be any real grounds on which to challenge a planning application that consists of new shopfronts and the creation of a small arcade - so Lambeth will be able to honestly say; 'we can't stop it', and then many people will think its a done deal.
The key is surely to keep it a political issue - keep piling on the pressure that 20k petition signers give, and make some clear demands. Lambeth have a great deal riding on the Town Centre project, and must be made to understand that it might be de-railed (see what I did there?) if they don't put pressure on NR to act decently.
IMHO, demands need to include;
1 - proper consultation on the plans BEFORE planning application is made - ie NR talk to the traders about what size unit they want and where so that phasing can means something - see point 3
2 - legally guaranteed right of return (ie not just PR statement) - for which a money deposit is paid (this means there would be a contact that NR must uphold)
3 - A phased/rolling programme of refurbishment - not one big job, so that businesses are not re-locating for a year, but can move into newly refurbished units as they become available - this will mean that the traders need to discuss among themselves who needs what BEFORE talking to NR, to avoid divide and rule (actually, the moment NR start divide and rule tactics - talking to individual traders and making them 'special deal' offers - then we know we are really winning).
I saw the lawyer get a bit of a kicking back there, and I understand why, but I do think it will be very sensible if most/all of the traders club together and are represented by a single law firm - preferably one which will do some pro-bono work for the good publicity. I'm sure there would be a good response for a fighting fund. A barrister in our road wrote NR a strong letter about this - I could ask him if he had any ideas on firms to approach.
