2013 – Disagreements between Spain and the United Kingdom Government re-surfaced in July 2013, initially after the Gibraltar Government placed a number of concrete blocks in the sea off the coast of Gibraltar, intending to form an artificial reef. The Spanish Government protested however stating that it had a negative impact on fishing in the area, restricting access for Spanish fishing vessels. At the end of July the Spanish Government introduced extra border checks for people going in and out of the territory into Spain. The British Government protested as the checks were causing major delays of up to seven hours while people waited to cross the border, and on 2 August the Spanish Ambassador was summoned to the British Foreign and Commonwealth Office in London to discuss these developments.
