But is the interpretation of the original LXB any clearer?
the piece by insider media at least gets to the point in a layman's terms kind of way.
the original is ambiguous but it is clear without doubt LXB had the leasehold interest and it is them who have given it up. Morrisons cannot give up something that was not theirs. Unless we refer to the lease ( tennant), which this is not
Definition of leasehold interest referred to as landlord:
leasehold interest is, on the other hand, a temporary right to occupy land or property. A person who owns the freehold interest in a property may grant a lease on it to another person. This creates a relationship of Landlord and Tenant (or Lessor and Lessee). The lease will be a lengthy, written, legal document based on property and contractual law which sets out the rights and obligations of both the Landlord (Lessor) and Tenant (Lessee).
Although the lease on any property will be a complex document, the basic principle is that it will give the Tenant (Lessee) the right to occupy the property for the period specified in the lease. The lease will normally specify that the Landlord (Lessor) will have to allow the Tenant (Lessee) ‘quiet enjoyment’ of the property provided that the Tenant (Lessee) in turn observes their duties under the lease. The principal duty normally being to pay the rent specified in the lease to the Landlord (Lessor).
