(ANSA) - ZAGREB - Four days ahead of the elections in Croatia, the election campaign heats up, amidst accusations, cheap shots and fiery appeals made to the electorate that, according to surveys, is basically split in two. Therefore, Sundays's vote looks set for a photo-finish. However, nobody made concrete promises or submitted clear economic programmes.

The Social Democrats, who have been ruling since 2011, have called their center-left coalition ''Croatia is growing'' by focusing on the country's macro-economic performance over the last 6-7 months, almost positive after six long and difficult years of recession and stagnation, including GDP data, industrial production, exports and employment.

The centre-right opposition leader, Tomislav Karamarko, former secret service director and interior minister in one of Sanader's cabinets, responded by accusing the premier of being ''in love with himself, arrogant, incompetent, a man who has run up massive debts totalling 13 million in four years, ruining the economy and forcing a hundred thousand young people to emigrate''. Just six months ago, the victory of the centre-right was taken for granted, with a gap between the two blocs of about 10%. The latest polls show, however, that the outcome is on a knife's edge: Milanovic is given 30-33% of the vote and Karamarko 32-35%. (ANSA).
