"A number of investigations are underway, and if there are too many violations, we will indeed have to question the overall outcome of the elections. This particularly applies to the parties which seemed suspicious and lacked transparency in the first round, they should have it in mind – I have a constitutional right to turn to the Constitutional Court, if we see that the number of violations is too big," the president said after casting her ballot early at the Vilnius city municipality on Wednesday.
Grybauskaitė voted in the single-mandate constiuency of Antakalnis where the Seimas mandate will go to either conservative leader Prime Minister Andrius Kubilius or Aurelija Stancikienė of the Path of Courage party.
Lithuanian prosecutors are investigating 18 violations reported during the first round of elections.
The most heated public reaction was triggered by the suspected vote buying in prisons. The Criminal Police Bureau has brought suspicions against Labour Party candidate Viačeslav Zdanovič.
The Central Electoral Commission has annulled election results in Zarasai–Visaginas where the first round secured the majority vote to Algimantas Dumbava of the Order and Justice Party, leaving Rimvydas Podolskis of the Labour Party a runner-up. The electoral body ruled that Podolskis grossly violated the Law on Elections to the Seimas by bribing voters.
Grybauskaitė has already turned to the Constitutional Court over the election results. On Tuesday, she asked the court to evaluate the Central Electoral Commission's move to invalidate election results in Zarasai-Visaginas single-member constituency.
The second round of elections is scheduled for Sunday.
