131.Section 75 specifies which tenants are qualifying tenants for the purposes of acquiring the right to manage.  These are effectively any tenant of a flat under a ‘long lease’ (as defined in sections 76 and 77), subject to the proviso that there can only be one qualifying tenant per flat.  Business tenants cannot be qualifying tenants.
