Macedonia has been warned that today’s presidential election is its last chance to prove it is worthy of a place in the international community. NATO and the European Union say the chance of early membership talks will be lost if this vote falls below accepted norms of fairness and transparency.Seven candidates are vying for the largely-ceremonial presidency, with Professor George Ivanov leading the polls. Mayors and city councils are also being selected today. The voting comes a year after chaotic parliamentary elections, which left one person dead and several injured. Progress has been made on ethnic relations, but one Western diplomat said simply that today’s vote must be spotless.
