PROTECTION OF ALLOTMENTS
Hi everbody, as you can see i'm a newbie on this site. I have had a good look round and you all seem really nice folk. I live in Surrey in a part that comes under greater London (if it still exists) and there is a thing called the Allotment Regeneration for London. This says that councils have a duty to create, where possible allotments. Not sell them.
In Aunt Sallys link,just a few paragraphs earlier,Nos
56 and 57 as per site says[]We note that allotments form an important part of leisure provision and this should be reflected within a local authority's Leisure Strategy[94] and Local Agenda 21 initiatives.
Therefore i would think its national and a petion would have to be looked at due to the fact its Parliament doing the saying. I know if it was tried at our site the gang would certainly act up.
Espescially now allotments will be needed for many to get any kind of fresh veg.
