asked the Secretary of State for Foreign Affairs how many British citizens, other than official persons, are registered at the British Embassy in Moscow as residents in the Union of Soviet Socialist Republics; and what evidence he has as to restriction on their freedom to leave that country.

Sixty-two British subjects, other than official persons, are known by the British Embassy in Moscow to be living in the U.S.S.R.; of these 28 also possess Soviet citizenship. I have no knowledge of restriction on the freedom of British subjects, other than dual nationals, to leave the U.S.S.R., although exit visas are required. British-Soviet dual nationals are subject to the same regulations as other Soviet citizens, and have in a number of cases been unable to leave the country.
