HC Deb 30 April 1941 vol 371 c427
43. Sir Leonard Lyle

asked the Minister of Supply whether he is satisfied with the output of heavy tanks, and with the provision of spare parts for those in use?

The Minister of Supply (Sir Andrew Duncan)

I am glad to say that the output of heavy tanks has shown and is showing continuous and gratifying expansion. A definite proportion of spares is an essential part of the programme, but the extent of that proportion must always be adjusted in accordance with operational experience.
