Some great news. Following the submission of my case to London Tribunals, I received a letter from Ealing Council saying that they have investigated the case and decided not to contest my appeal and cancelled the 2nd PCN.
I also received another letter stating they accepted my representation for the 1st PCN and cancelled that too.
Thank you to everyone who commented, your help was invaluable.
Please keep up the great work you have been doing on this forum, it really does make a difference.
