Do the authorities have a duty to move on UEs camped on private land?

Do the Council or Police have a duty to move UEs on when they are camped on private land without the landowner's permission?

If the unauthorised encampments are on private land it is primarily the landowners' responsibility to deal with the issue. Kent County Council and the relevant District Council will provide advice and help if asked to do so by the landowner. New guidance issued by the office of the Deputy Prime Minister/Home Office says that within the overall strategy for managing unauthorised camping, the local authority might consider acting more directly against encampments when requested by a private landowner. The Police will of course tackle all reports of crime (but not trespass) wherever they are reported.
