The National Allotment Society is aware that allotments are vulnerable to threats from developers looking for green land to build on – signing this petition can only serve to reinforce to government the importance many people place on allotments and the passion that they feel about them, but we feel that we must point out that the particular threat that this petition refers to is no longer current. So it is unlikely it would ever be debated in the House of Commons as the issue has already been resolved.
