The message
from The Reid contains these words:

I just heard my council as decided to close down most of its
allotments, including mine. Any comments on opposing this
welcome.

I`ve read an awful lot of stuff on the legal`s regarding allotments and
it`s not easy to close them down with no alternative available.

It could be they just do not want the hassle of running it anymore.
Possible suggestion is to go self managed.
