HC Deb 25 April 1940 vol 360 c390W
Mr. Thurtle

asked the Secretary of State for War whether it is a fixed and invariable practice of his Department not to engage any British subject whose parents were not both natural-born British subjects?

Sir E. Grigg

It is a general rule not to engage a British subject whose parents were not both natural-born British subjects, but exceptions are, and have been, made in special cases.
