More recently, there has been (and remains) a persistent dispute between Spain and Gibraltar over British sovereignty in the Bay of Gibraltar. Spain claims not to recognise British sovereignty in the area save for a small portion around the Port of Gibraltar, but the UK has asserts a normal limit around Gibraltar, with a demarcation in the middle of the bay. This claim contradicts, according to the Spanish government, the treaty of Utrecht of 1713, by which Spain ceded to Great Britain the city and port of Gibraltar and the internal waters of that port, without granting any territoriality over the surrounding waters in the Bay of Algeciras.
