I suppose the key phrase is:
"We are not looking to change the terms of the lease. "
On the surface of it, that sounds like the Council aren't holding anything up ......... unless of course, the Spanish actually want something to be changed, and the Council are against it.
What might that be? The rental payments surely wouldn't be referenced in there (they'd be in a separate agreement) so there must be another clause that's causing the delay ...........................that's if there is an issue with the lease.
Let's hope PK advises further soon.
