Salvadorian President Elias Antonio Saca requested on Friday international observers to point out any irregularity in the country's presidential elections on Sunday, according to news reaching here from San Salvador.
Saca extended a warm welcome to all international observers in the Presidential House, calling for their support for the democratic advances in El Salvador.
"Feel free to point out our mistakes, the failures in the system," Saca said.
The observation mission attests the transparency of the electoral process, the president added.
More than 4.2 million Salvadorians will vote on Sunday for the country's leader for the next five years.
Presidential candidates include Rodrigo Avila from the ruling right wing Nationalist Republican Alliance (ARENA) and Mauricio Funes from the left wing opposition party Farabundo Marti Front for the National Liberation (FMLN).
Among the observers, 90 come from the European Union (EU), 80 from the Organization of American States (OAS) and 43 from the Inter American Union of Electoral Organism, which represents 28 countries in the Americas.
