In reply to Jon Read:
Given how much stuff could be accessed using a driving licence or a passport I am not sure I would feel comfortable sending it to someone just because they are a landowner.
Surely it would be less onerous on them and remove the massive data protection compliance risk which they have created if they have a list of names and if the landowner comes over and anyone is there who can't show photo ID confirming they are on the list they have to leave.
The BMC have done good work in regaining us access, although I find the landowner's preferred solution here a bit concerning.
