I am writing to make a freedom of information request as follows

Please can you provide the number of unauthorised encampments that have occurred in your administrative area for the years 2016, 2017 and 2018 to date. By unauthorised encampment i mean any trespass by a person or persons where caravans, mobile homes or motor homes are stationed on public or private land.

I have attached a very simple table in excel which i would be grateful if you could reply having filled it out.
