My Lords, is there any overall consistency about who pays rent for the use of overseas bases? I understand that the American Government pay the Japanese Government for the use of Okinawa, which is a substantial base. As far as I am aware, the United States does not pay the British Government for its bases in Britain, or for its use of Ascension Island and listening posts in Cyprus. They are covered simply by exchanges of letters—which, I understand, have since been lost. Why is it that in Diego Garcia, where, as I understand it, there are fewer than 20 British personnel and a much larger number of American personnel, we are paying the rent to the Mauritians, not the Americans?
