Greek President Karolos Papoulias will attempt to persuade divided party leaders Tuesday to accept his proposal for a government of prominent non-politicians to steer the country and avert new elections, as doubts mount that Greece can avoid an exit from the eurozone. Papoulias will meet with all leaders of parties represented in Parliament except for an ultra-nationalist party in Athens, said Evangelos Venizelos, the leader of Pasok, the third-biggest party.
