As per others - yes he effectively is, via his company BSC Ltd.
However if he is true to reputed past "form", he will be trying to avoid responsibility and cost for the needed improvements and repairs, either by maintaining they should be done and financed by others, or by just doing nothing in response to requests from his tenants.
This is somewhat different from the stadium car park, which BSC under the planning requirements of City Council, was supposed to have tarmacked over with parking spaces properly marked. So if anyone incurs an injury by accidentally stepping into a pothole whilst walking across it, you know who is liable. However, the chances of actually getting any compo from BSC are slim, but you could have a better chance with the Council if they've failed to enforce the requirement.
