Solo – Puan Maharani, Megawati Soekarnoputri's daughter, on Sunday blamed the electoral roll fraud in the April 9 legislative elections for the defeat of the Indonesian Democratic Party for Struggle (PDIP).

Puan said supporters of presidential candidate Megawati and running mate Prabowo Subianto must not make the same mistake in the July 8 presidential election.

Megawati is the PDI-P chairwoman, while Prabowo is the chief patron of the Great Indonesia Movement Party (Gerindra). "The permanent voter list will be the key to winning the presidential election," she was quoted by Antara news agency as saying at a campaign in Solo, Central Java.

"You all have to make sure that you have been registered by the General Elections Commission."

The Democratic Party won the April 9 legislative elections with 20.9 percent of votes, followed by the Golkar Party with 14.5 percent and the PDI-P with 14 percent.
