In May 1968, intercommunal talks began between the two side under the auspices of the Good Offices of the UN Secretary-General. Unusually, the talks were not held between President Makarios and Vice-President Kucuk. Instead they were conducted by the presidents of the communal chambers, Glafcos Clerides and Rauf Denktaş. Again, little progress was made. During the first round of talks, which lasted until August 1968, the Turkish Cypriots were prepared to make several concessions regarding constitutional matters, but Makarios refused to grant them greater autonomy in return. The second round of talks, which focused on local government, was equally unsuccessful. In December 1969 a third round of discussion started. This time they focused on constitutional issues. Yet again there was little progress and when they ended in September 1970 the Secretary-General blamed both sides for the lack of movement. A fourth and final round of intercommunal talks also focused on constitutional issues, but again failed to make much headway before they were forced to a halt in 1974.
