MEXICO CITY - Mexico's electoral authorities said on Wednesday that votes from some 54 percent of the polling stations countrywide were being recounted.

The recount decision was made as a response to the claims of fraud and demands for recounts in Sunday's presidential race.

However, the Federal Electoral Institute (IFE) officials said the recount would not significantly change the preliminary results, which indicated that Enrique Pena Nieto, candidate of the Institutional Revolutionary Party (PRI) and a former governor of Mexico State, won the race with a comfortable margin of 6 percentage points over his arch rival Andres Manuel Lopez Obrador.
