Following the sudden death of Ambassador Tuomioja in August, Galo Plaza was appointed Mediator. He viewed the problem in communal terms. In March 1965 he presented a report criticising both sides for their lack of commitment to reaching a settlement. While he understood the Greek Cypriot aspiration of "enosis", he believed that any attempt at union should be held in voluntary abeyance. Similarly, he considered that the Turkish Cypriots should refrain from demanding a federal solution to the problem. Although the Greek Cypriots eventually accepted the report, despite its opposition to immediate "enosis", Turkey and the Turkish Cypriots rejected the plan, calling on Plaza to resign on the grounds that he had exceeded his mandate by advancing specific proposals. He was simply meant to broker an agreement. But the Greek Cypriots made it clear that if Galo Plaza resigned they would refuse to accept a replacement. U Thant was left with no choice but to abandon the mediation effort. Instead he decided to make his Good Offices available to the two sides via resolution 186 of 4 March 1964 and a Mediator was appointed. In his Report (S/6253, A/6017, 26 March 1965), the Mediator, now rejected by the Turkish Cypriot community, Dr Gala Plaza, criticized the 1960 legal framework, and proposed major amendments which were rejected by Turkey and Turkish Cypriots.
