There is a Tesco leaflet being distributed in Whittlesey at the moment. I don't know how many people will receive it, so I was going to publish it when I got a chance - but it is probably just as easy top link to the Cambs Times article about it, which is here.
I would add the same qualifier as I have done when I linked to the Sainsbury report over transport access to Station Road, that this is one side of the argument. In particular, there has been some dispute about the legality of removing planning permission on a site that is in a separate location to the current planning application.
I am still distributing a supermarket survey around Whittlesey North, I am getting about a 12% return rate which is perfectly acceptable. I will summarise the findings so far over the next week or so.
