§ Mr. Michael McNair-Wilson
asked the Secretary of State for Foreign and Commonwealth Affairs upon which treaty the United Kingdom's claim to Gibraltar rests; and if he will detail the relevant passages.
§ Mr. Whitney
The treaty upon which the United Kingdom bases its title to Gibraltar is the treaty of peace and friendship between Great Britain and Spain, signed at Utrecht, 2–13 July 1713. The relevant passage (article X) is detailed on page 116 of document 166, the Seventh Report from the Foreign Affairs Committee Session 1980–81, 'Gibraltar: The Situation of Gibraltar and United Kingdom Relations with Spain', a copy of which can be found in the Library.
