§ Mr. Giles Shaw
In 1978–79 overall output per man-shift was 2.24 tonnes. From 1979–80, on a slightly different definition, revenue output per man-shift has been as follows: 1979–80, 2.31 tonnes; 1980–81, 2.32 tonnes; 1981–82, 2.40 tonnes; 1982–83, 2.44 tonnes.
§ Mr. Shaw
I understand my hon. Friend's point, but I pay tribute to the fact that at least the movement is significant and in the correct direction. The House must also be aware that there is a limit to how far the capital investment available can stretch in seeking to cover every eventuality. The Coal Board must concentrate it where it is most needed and where it can be used most profitably.
