Founding president Sukarno's son Guruh Soekarnoputra announced Saturday his bid for the Indonesian Democratic Party of Struggle's (PDI-P) top job, which may lead him to a possible showdown with the incumbent and elder sister Megawati Soekarnoputri.

Guruh shrugged off the possible battle between siblings, telling his supporters who gathered at his residence on Jl. Sriwijaya Raya in South Jakarta that he was out to join the race in April.

"I am ready to contest the election to respect your aspiration. I consider your trust a call of duty," he said as quoted by kompas.com.

He said his nomination was driven by his concern about the party's poor performance in the last two elections and his aim to restore the party's past glory.

"The party's votes dropped from one election to another, which indicated something had gone wrong with the party. We have to fight for changes and resist a status-quo," he said.

Guruh, who is a noted artist, said Megawati as his sister had given him her blessing.
