The exchange to which my hon. Friend refers arose out of quite exceptional circumstances which are not likely to be repeated, and there is therefore no likelihood of any further exchange on these lines. Last summer His Majesty King Ibn Saud requested the Turkish Government to intervene with His Majesty's Government and the Italian Government in order to arrange by agreement the removal of some 800 Italian sailors who had been interned at Jedda, together with a small number of civilians by means of an exchange. We agreed to consider an exchange against a suitable number of British naval prisoners of war in Italian hands and to provide transport from Jedda. At that time it was understood that the total number of British naval personnel in Italian hands was less than the number of Italian naval refugees at Jedda. No question, therefore, arose of the length of captivity. When, subsequently, more British naval personnel were captured by the Italians it was felt to be inadvisable to make fresh conditions in order not to risk delay in reaching an agreement. It was also decided, in order to facilitate agreement, to offer to include some 40 Italian civilians, and also a smaller number of German civilians, mostly merchant seamen, who were also interned at Jedda, in exchange for an equivalent number of British. I am glad to be able to confirm that the exchange was completed at the Turkish port of Mersin on 21st March and to take this opportunity of publicly thanking the Turkish Government for the valuable help which they have given in this matter.
