Read between the lines and what it basically comes down to is this
"We can move a few of you next door to the legal site, we can move a few of you to sites around essex, a few more to the next county, and a few more into the county after that and so and so forth"
They were not presented with a solution that kept the community together. Because they didn't want the community together, they wanted it split and moved on elsewhere to be somebody elses problem.
The whole greenbelt thing is BS too. Look at the moves by the new coalition government to scrap the whole greenbelt restrictions to encourage self builders and the like to build more houses as we currently have a massive housing shortage in this country. There is massive overhaul in the planning regulations coming.
Probably one of the reasons they want to evict them now before the camp can be made legal.
