Spanish foreign minister Jose Manuel Garcia-Margallo will use a trip to Buenos Aires next month to raise the possibility of forging a joint diplomatic offensive with the South American country over the disputed territories, sources told Spain's El Pais newspaper.
Spain's foreign ministry was also discussing whether to take its complaints over Gibraltar to the United Nations, the newspaper reported on Sunday.
The sources did not specify whether Spain would ask the UN to back a request for Britain to give up sovereignty or just adhere to certain agreements.
It could take its petition to the Security Council or take up the matter with the UN General Assembly.
Spain is also considering the option of denouncing Gibraltar to the International Court of Justice in the Hague for its "illegal occupation" of the isthmus - the strip of land connecting the peninsula to the mainland that was not included in the 1713 Treaty of Utrecht. » | Fiona Govan, Madrid | Sunday, August 11, 2013
