By Ivana Sekularac and Matt Robinson BELGRADE (Reuters) - Serbia's center-right Progressive Party attempted to cement its grip on power for the next four years in a snap election on Sunday, promising an economic overhaul of the ex-Yugoslav republic as it embarks on talks to join the European Union. Opinion polls suggest the party may win more than 40 percent of the vote, a haul unprecedented in the almost 14 years since Serbia came in from the cold with the ouster of strongman Slobodan Milosevic. Party leader Aleksandar Vucic, 44, a former ultra-nationalist and once feared Milosevic-era minister who converted to the pro-EU cause in 2008, is likely to become prime minister. The Progressive Party (SNS) forced the snap election after just 18 months in coalition government, saying it needed a stronger mandate to overhaul Serbia's shaky finances.
