HC Deb 24 March 1975 vol 889 c6W
Mr. Trotter

asked the Secretary of State for Employment which ports are not in the dock labour scheme.

Mr. Booth:

The best estimate available is that at least 600 places might be defined as ports for the purposes of the dock labour scheme but are not covered by it. A very large number of these are not in active use, or could be used only by very small craft or are used only by fishing vessels.
