345.Section 218 disapplies landlord and tenant law from Public-Private Partnership leases so that London Underground and a PPP company will interpret their rights and duties solely in accordance with the PPP contract and lease.  The purpose of the section is to enable the public sector to recover all the real property it needs to continue services when a PPP contract ends, without the delays inherent in established landlord and tenant practice.
346.Section 219 disapplies the normal requirement to register title with the Land Registry for leases of over 21 years.  This is intended to save the considerable time and money which would otherwise be required to produce copies of suitable plans, deeds, etc.  The effort of complying with the registration requirements would be of little or no benefit because of the very restricted opportunities for PPP companies to transfer or otherwise deal with the land.
