The prime minister-elect will be under intense pressure to launch a stronger administration than the preceding government, which fell after less than two years, EuroNews.net noted Sunday. Italy's slowly stagnating economy will reportedly be a major concern.

Berlusconi, representing the center-right, has been steadily leading in opinion polls and predicts he will return as prime minister for a third time, EuroNews.net said.

Center-left opponent Walter Veltroni, has run on a platform of change, the Web site said. Both candidates have suggested tax cuts and cited the need for an increased police presence.

About one-third of eligible voters are predicted to cast ballots Sunday, the first day of the two-day election process.
