evidence: Spain and the UK continue to spar over the territory. Throughout 2009, a dispute over Gibraltar's claim to territorial waters extending out three miles gave rise to periodic non-violent maritime confrontations between Spanish and UK naval patrols and in 2013, the British reported a record number of entries by Spanish vessels into waters claimed by Gibraltar following a dispute over Gibraltar's creation of an artificial reef in those waters. Spain renewed its demands for an eventual return of Gibraltar to Spanish control after the UK’s June 2016 vote to leave the EU, but London has dismissed any connection between the vote and its continued sovereignty over Gibraltar.
