A leasehold is in principle the best way to secure the football club as it makes any terms and restrictions of use far more robust, and ultimately a lot more enforceable. The council will be minded to protect the club as a cultural asset and it would carry significant political weight, in terms of fans being able to hold them to account should they ever cause harm the club.
What is obvious here, especially with this additional break, is that they’re going to allow the club to build a stadium subject to planning approval. It’s going to be a ‘yes’.
