To ask the Secretary of State for Transport how much public money has been spent to date on research, development and associated costs on the Jubilee line extension.

Up to the end of the financial year 1991–92, some £100 million of public money had been spent on advance works, design, parliamentary work, land purchase, property purchase and project management for the Jubilee line extension. It is estimated that a further £18 million was spent in the first 12 weeks of this financial year.

To ask the Secretary of State for Transport when he expects the crossrail and the Chelsea-Hackey line proposals to be at a stage of development comparable to the present Jubilee line extension scheme.

These three projects are expected to proceed sequentially. Powers exist to build the Jubilee line extension; public, though not private, funding is in place. It will be some years yet before crossrail is ready to build: that will depend on the parliamentary process and the availability of funds. The Chelsea-Hackney line will follow on as permitted by the availability of funds, the capacity of the construction industry and the ability of the capital to absorb further major construction works.

To ask the Secretary of State for Transport what is his estimate of how many jobs will be created by the Jubilee line extension.

The construction of the Jubilee line extension is estimated to create direct employment on-site on civil works for some 4,000 people and off-site in manufacturing and supply of the order of five times as many more people.
