§ Mr. Deakinsasked the Secretary of State for Education and Science what study has been made of the heritability of the liability to cancer in human beings; and with what result.

§ Mr. John E. B. Hillasked the Secretary of State for Education and Science whether she will increase the minor works programme allocated to Norfolk to relieve serious overcrowding and inadequate toilet or other facilities in primary schools.
§ Mrs. ThatcherYes. I have informed 18 local authorities which fall into this category or which have other special needs that their allocations for 1971–72 and 1972–73 will be increased. Details are given below. Additional resources will also be made available for minor works at aided schools, which are administered directly by my Department. The total addition to minor works allocations in England will be £1.875m. in 1971–72 and £2.075m. in 1972–73. The School building programme for England at the present cost limits will now be £176m. both in 1971–72 and 1972–73, and the total for England and Wales £188m. in each year.
tically determined, and a very small increased rate for relatives of those with certain cancers, for example of the colon, the contribution from genetic causes is thought to be very small.
