Might be an idea to share the Freepost address here for the benefit of anyone who didn't get one of these letters and wants to, erm, communicate with Mr Farage?

That looks utterly rank. Why would you even go there when actual bread and cheese exist?

Yeah, sadly. I had this with the Tories. I sent a cease & desist letter & Subject Access Request (covered by GDPR) to stop them & force them to send me copies of all info they held on me. Wastes a bit of their time/money, and it was quite interesting to see how wrong their voter analysis of me was!
