Former President Megawati Sukarnoputri was re-elected chairwoman of the Indonesian Democratic Party of Struggle during the opposition party's national congress in Bali on Thursday.

She will be chairwoman of the party until 2015, after the next legislative and presidential elections scheduled for 2014, increasing the chances she will have another stab at running for president despite two resounding defeats in previous polls.

That likelihood was given further credence with the party's decision not to elect a deputy chairperson, with speculation prior to the congress that the position would be filled by Megawati's daughter Puan Maharani or son Prananda Prabowo.

The party is still expected to elect a secretary general and three deputies.
