The precise figure is 'over 36%' of the Republic of Cyprus's territory, slightly more than the 'one third' stated by the MEP — the claim is a conservative approximation rather than an overstatement.
The casus belli is a conditional declaration made by the Turkish parliament in 1995, triggered only if Greece unilaterally extends its territorial waters in the Aegean to 12 nautical miles; it is not an unconditional or currently active threat of war.
The northern part of the island is administered by Turkish Cypriots and self-proclaimed the 'Turkish Republic of Northern Cyprus' in 1983, recognised only by Turkey.
