asked the Parliamentary Secretary to the Ministry of Works whether he has considered the protest sent to him by the Gloucester and South Midlands Area of Building Industry Distributors that, in the contracts for the construction of houses for agricultural workers, it is specified that certain materials are to be supplied by named firms outside the area; and, as this is unfair to local firms who have these materials in stock, will he amend the contracts so as to give local builders' merchants the opportunity to supply materials required in their areas?
