Romanian voters go to the polls Sunday in presidential and parliamentary elections.

Opinion polls indicate Socialist Democrat Prime Minister Adrian Nastase and Bucharest mayor Traian Basescu - the nominee of the Justice and Truth alliance- head the list of 12 presidential candidates. If no candidate wins a majority a runoff is scheduled for December 12.

Candidates of the Socialist Democrats and Justice and Truth alliance are also in tight races for seats in the country's parliament.

Sunday's balloting comes as the Socialist Democrats fight new charges of corruption against the governing party. Documents said to be transcripts of top-level meetings are reported to highlight abuses of power. Prime Minister Nastase calls the documents fake.

Corruption is a major problem in Romania. The government has been seeking to implement reforms in hopes of moving the country towards European Union membership in 2007.
