HC Deb 09 December 1991 vol 200 c334W
23. Mr. Alison

To ask the Secretary of State for Energy by how much British Coal's productivity has changed since 1984–85.

Mr. Wakeham

Productivity in 1984–85 was exceptionally low due to the miner's strike. Compared to 1983–84, the year preceding the strike, productivity in British Coal mines has increased by an impressive 105 per cent.
