Two or three years ago, about a year before I got my plot, the developers were going to take half the plots to build on.
One lady who had just managed o get a plot was a bit upset to say the least. Before the general meeting with the planners she found out all the legalities and why's and wherefores of the situation and at the meeting she slammed them. The planners offered to build all the remaining plot holders brick sheds if they voted against the rest of the holders.
This was taken as blackmail by everyone and so, to cut a long story short (I don't know all the details), the council and the planners were beaten and not only are all our plots safe but the lady in question is now the allotment manager.
But there's more... Just got the news today that she's managed to bully the council into letting us have an adjacent piece of land, enough for another 17 full size plots including them clearing and setting it out with a car park.
Hows that for a result? ;D
Just show what a decent allotment manager with balls can do...
