The refurbishment and modernisation of the tube in London is of the utmost importance. That is why we have presented the public-private partnership as the best means of delivering cost-effectively the modernisation that is needed. The operation of trains will remain in the public sector, health and safety will remain independently in that sector, and discussions must take place—and are continuing—with Mr. Kiley and with Transport for London. It is in the interests of Londoners and the future of the modernisation of our tube that those talks succeed, and that through the public-private partnership we avoid the overruns on costs and time that characterised the Jubilee line extension.
