Thank you everyone for your valued advice. I've told my family and close neighbours about the letter and their first instincts were to 'go and sort him out!' (especially the males!). But that's not a good idea obviously.
The letter picked out various lines in my objection, taking them completely out of context or deliberately misinterpreting them, which makes it all so stupid. As for the privacy issue, I read the council's policy and apparently the contents of my objection can be in put the public domain, but definitely not my private details. In fact a lovely councillor contacted myself and my neighbour and offered to represent us at the planning appeal in order to keep our identities private, because this bully is well known to them. Apparently his behaviour was very aggressive and threatening at the appeal too.
I've thought all weekend about dialling 101 to speak to the police about it, but I'm not able to speak to anyone yet without getting tearful! Silly I know but this has come after recently losing my 97 year old mum and then my cat, so I'm not feeling very strong at the moment. I will take your advice though and contact them. Thank you all again.
Do you get emotionally attached to the plants in your garden ?
