To ask the Chancellor of the Exchequer what Treasury guarantees have been given in respect of the funding of the proposed Jubilee line extension; and if he will make a statement.

The Treasury has issued no guarantees in relation to any part of the funding of the Jubilee line extension. Government funding has, however, been earmarked for the public sector contribution to the cost of the line—see, for example, "The Government's Expenditure Plans for Transport 1993–94 to 1995–96", Cm 2206.
