Argentine President Cristina Fernandez de Kirchner has ended speculation about her political future, announcing Tuesday that she will run for reelection in October.

Although many polls suggest she is likely to win a second term, it had been unclear whether she would run because of recent health problems. President Fernandez cancelled a visit to Mexico for medical reasons in April and took a brief medical leave in January.

Argentina has enjoyed continued economic growth under Mrs. Fernandez, who succeeded her husband as president in 2007. Former president Nestor Kirchner died in October 2010 of heart failure.

President Fernandez has not yet named a vice presidential running mate.
