The Transport Secretary said he will publish early next month an independent assessment of the private-sector bids to take over the Underground being carried out on behalf of the Government by City accountants Ernst and Young. If the bids fail to pass the value-for-money tests compared with a taxpayer-funded alternative, then PPP faces the axe. This could mean all or some of the contracts to run the Tube, which are about to be agreed by the Government, being handed over to London Mayor Ken Livingstone and his transport commissioner, Bob Kiley.
