A high court judge is set to become Greece's first female president in a vote on Wednesday after two opposition parties sided with the center-right government's nomination.
Katerina Sakellaropoulou, 63, has served as president of the Council of State, a top administrative court, for the past 15 months.
A government spokesman, Stelios Petsas, on Tuesday said Sakellaropoulou was set to receive "well beyond" the 200 votes needed for her election in a vote scheduled in the 300-seat Parliament on Wednesday.
Two center-left opposition parties have already backed Sakellaropoulou's nomination, raising the total number of lawmakers from parties declaring support to 266.
Greece has a historically low level of women in senior positions in politics. In the current cabinet, all but one of the 18 senior positions are held by men.
The president holds a largely ceremonial position and serves a five-year term. If elected, Sakellaropoulou will succeed President Prokopis Pavlopoulos, a 69-year-old veteran conservative politician and academic.
