HC Deb 03 December 1964 vol 703 c106W
59. Mr. Walder

asked the Secretary of State for the Home Department if he will introduce legislation to prevent the contracting of marriages within the bounds of consanguinity by adopted children in ignorance of their common parentage.

Mr. George Thomas

The chance of this occurring seems to my right hon. Friend to be insufficient to justify the establishment of the complicated machinery that would be required to prevent it.
