asked the Minister of Transport what progress has now been made in the construction of the Victoria Line; and what length of rail has so far been laid.

London Transport inform me that 21½ of the 25 miles of running tunnels have been completed, and about 75 per cent. of all the civil engineering work. Little rail has so far been laid; the main work on this is due to start this autumn.The estimated date of late 1968 for opening the first section of the line still stands.
