Indonesian opposition leader Megawati Sukarnoputri on Saturday rejected President Susilo Bambang
Yudhoyono's landslide re-election win and will challenge the results in court, a spokesman said.
Megawati's campaign will lodge a challenge to the results of the July 8 poll with the Constitutional Court, by
alleging widespread irregularities including millions of people left off voter rolls, spokesman Gayus Lumbuun said.
"Because there are still unresolved legal issues, we are rejecting the presidential election results from the KPU
(election commission)," Gayus Lumbuun said.
Official results announced by the commission on Saturday gave the liberal ex-general Yudhoyono 60.8 per cent of the
vote, far ahead of ex-president Megawati with 26.8 per cent and Vice-President Jusuf Kalla with 12.4 per cent.
The Megawati campaign boycotted the official signing of the results at the election commission office.
Kalla's campaign will also launch a Constitutional Court appeal over voter list irregularities, but has not yet decided
whether to accept or reject the results, news website Viva News reported.
Yudhoyono, who defeated Megawati in Indonesia's first direct presidential election in 2004 on an anti-corruption
platform, is credited with ensuring stability and economic growth.
