LUL has received requests for over twenty Direct Agreements from Tube Lines and, until recently, copies of the sub-contracts were not being provided with these requests. In Spring 2004 LUL exercised audit rights to check compliance with the PPP contract requirements in this area. Tube Lines has now agreed to remedy deficiencies identified in the audit by various dates over the next few months. Since then, Tube Lines have generally submitted copies of the sub-contracts with requests for Direct Agreements but no agreement has been reached on the provision of variations.
