Camelia Pasandaran – Still crying foul over the July 8 presidential election, runner-up Megawati Sukarnoputri will likely refuse to sign the final official results slated to be announced this week, a senior member of her campaign team said on Monday.

Megawati's poll observers in several provinces, including Jakarta, East Nusa Tenggara, West Nusa Tenggara and North Sumatra, have already refused to put their signature on final provincial vote tallies, citing irregularities.

The General Elections Commission (KPU) has invited the three presidential candidates to attend a ceremony once the final results are tabulated, which officials say will be held sometime between Tuesday and Thursday. President Susilo Bambang Yudhoyono appears to have clinched re-election with more than 60 percent of the vote.

However, Megawati and her running mate Prabowo Subianto have rejected the results and are expected to boycott the event, said Arif Wibowo, a campaign team member.

"The election was far from being fair and honest and was against the principles of democracy. Why would we legitimize it given its condition?" he said, adding that Megawati would make a decision about the signing today.

She declined to sign the presidential poll result in 2004. KPU member Syamsul Bahri said the final results would be valid regardless of whether candidates signed them or not.
