LJUBLJANA (AFP) - Slovenians voted in a presidential run-off with opinion polls favouring former premier Borut Pahor, despite his support for government austerity plans that have brought thousands of protesters on to the streets in the recession hit eurozone state.  Pahor, 49, pulled off an upset in the first round on Nov 11 when he won almost 40pc of the vote ahead of the then favoured incumbent President Danilo Turk, 60, with almost 36 percent. On Sunday, he was expected to win with 60 percent ahead of 40pc for Turk, according to latest opinion polls published Friday. Pahor, who is backed by the centre-left opposition Social Democrats, appeared to have won voters over by admitting that some of his decisions as PM were wrong..
