Nicosia, Mar 22: Greek and Turkish Cypriot leaders go through the motions of an already doomed last meeting to forge a peace deal but arrangements are in place for their Greek and Turkish motherlands to take over the talks. After meeting almost daily since February 19, Turkish Cypriot leader Rauf Denktash and Greek Cypriot leader Tassos Papadopoulos have refused to budge on their key demands to reunite the Mediterranean Island. Disagreements primarily centre on territorial trade-offs and property claims. Under the United Nations peace plan for the island, if there is no agreement by today, four-way talks start on March 24 in the Swiss resort of Buergenstock on the shores of Lake Lucerne, with Prime Ministers Tayyip Erdogan of Turkey and Costas Karamanlis of Greece joining from March 28. U.N. Secretary-General Kofi Annan, mandated to fill in any unresolved issues on his power-sharing blueprint if the four-way talks come up short, joins the talks around the same time. br>''The presence of Greece and Turkey will give more impetus to negotiations but it is quite likely Annan will end up filling in many blanks,'' an Ankara-based EU diplomat said. The plan is put to a referendum of both communities on April 20. Bureau Report
