Losing Gibraltar would complicate British maritime zones

What would losing Gibraltar do to Britain's exclusive economic zone?

It would complicate Britain's maritime position, but it would cost far less than half of the British exclusive economic zone.

Losing Gibraltar would not remove half of Britain's exclusive economic zone. The territorial change would still make maritime claims and arrangements more complicated. It could also leave Gibraltar seeking a political settlement without any guarantee of a more favorable deal elsewhere. The diplomatic and maritime-boundary problem is real, but the numerical claim is exaggerated.
