Lawmakers in Greece are to vote again on the country's new president, in an attempt to break an impasse that could bring down the conservative government.

The vote in parliament scheduled midday Tuesday follows a ballot last week, when the government failed to gain enough support for its candidate, former EU commissioner Stavros Dimas.

The government needs to attract opposition support for Dimas to get elected, and at the weekend offered to set a timetable for an early general election before the end of 2015.

The left-wing Syriza party, leading in opinion polls, is demanding immediate elections, arguing that the country must renegotiate its bailout program.

The final round of voting takes place on Dec. 29, when failure to elect Dimas would force the government to dissolve and call elections.
