However, the division of power as foreseen by the constitution soon resulted in legal impasses and discontent on both sides, and nationalist militants started training again, with the military support of Greece and Turkey respectively. The Greek Cypriot leadership believed that the rights given to Turkish Cypriots under the 1960 constitution were too extensive and designed the Akritas plan, which was aimed at reforming the constitution in favour of Greek Cypriots, persuading the international community about the correctness of the changes and violently subjugating Turkish Cypriots in a few days should they not accept the plan. Tensions were heightened when Cypriot President Archbishop Makarios III called for constitutional changes, which were rejected by Turkey and opposed by Turkish Cypriots.
