From my previous link:
-- 'Why do Gypsies and Travellers camp on other people's land or develop land without planning permission?
There is a serious shortage of authorised sites for Gypsies and Travellers across the country with approximately one in five caravans on unauthorised sites. This has led to a growing tendency for Gypsies and Travellers to buy land and develop it without planning permission (unauthorised development) or camp on land that they do not own (unauthorised encampment).
The problem dates from 1994 when the duty on Local Authorities to provide appropriate sites was removed. In place of this, Gypsies and Travellers were encouraged to buy their own land and seek planning permission. In practice, however, this has proved unworkable, as many Local Authorities have failed to identify appropriate sites or to grant planning permission. In addition, Gypsies and Travellers, wanting a more settled lifestyle, have bought land where they could, rather than where it was most appropriate.
-- What is the Government doing about solving the problems created by unauthorised sites?
Gypsies and Travellers are a part of our society and need appropriate places to live, just like the rest of the community. If they cannot find an authorised site, their only alternative is to camp somewhere that is not authorised. So it is clear that the problem of unauthorised development and encampments can only be solved by the provision of more public and private sites.'
So there's the answer to your statement 'LPAs must consider the application, not the applicant. And that applies across the board.' The simple truth is that LPAs do listen to the campaigns against Travellers that are mounted by residents. Elected officials are sensitive to the fact that there are no votes in Traveller friendly policies, and pp is denied to Travellers due to local pressure.
