asked the Minister of Health whether he will introduce legislation to end the derating of productive industries and, instead, derate all working-class dwelling-houses?

No, Sir.

Does the Minister not think that the rents of working-class houses are far too high, and that there is an urgent need for the derating of working-class houses rather than the derating of industrial property?

That is a matter of argument upon which people may have different opinions.

In view of the fact that 200 local authorities have petitioned the Minister to do this, will he not go into the matter again?
