HC Deb 26 November 1914 vol 68 c1292
3. Mr. BUTCHER

asked the Secretary of State for Foreign Affairs what precautions are taken and what investigations are made before granting to persons of German and Austrian nationality who are naturalised in this country passports for visiting neutral countries such as Holland: whether he is aware that persons to whom such passports are given are thereby enabled to pass, and have in some cases actually passed, into the German lines in Belgium, and are enabled to communicate directly and in person with the German military authorities, and whether, in order to lessen the danger of information being in this way communicated to the enemy, he will take steps to ensure that no passports shall be issued to persons of German and Austrian nationality, even though naturalised, unless the Foreign Office are satisfied after strict investigation that the purpose for which the passports are sought is a proper and legitimate one?

The SECRETARY of STATE for FOREIGN AFFAIRS (Sir Edward Grey)

Passports are not granted to naturalised British subjects of enemy origin unless they produce documentary evidence that they have lost their enemy nationality. In the case of naturalised British subjects, special investigations are made, and passports are not granted if there is any ground for suspicion that they will be used for an improper purpose.
