After a real battle with the council I am pleased to be able to report that the missing footpath on Porterhouse Terrace in Pity Me has now been installed.
The short stretch of missing path which I have repeatedly asked the council to intervene and fix for two years was finally done after I raised the issue to the most senior officers in the Council and logged a complaint.
As I see it if you push and push, eventually, if you are right on something you will get it fixed.
