§ Mr. Delargyasked the Secretary of State for the Environment (1) what criteria he applies for the increase in toll charges on tunnels;
(2) what criteria he applied in increasing toll charges on the Dartford-Purfleet Tunnel.
§ Mr. CarmichaelThe local Acts under which the three English tolled tunnels, at Dartford, Mersey and Tyne, are operated specify the purposes to which toll receipts are to be applied. In considering applications for increases in tolls, my right hon. Friend requires to be satisfied, having regard to the general financial position and future prospects of the undertaking, that the tolls proposed will produce sufficient revenue for those purposes.
