JAKARTA - INDONESIAN opposition leader Megawati Sukarnoputri's campaign team refused to concede defeat on Friday to an apparent landslide election win by incumbent President Susilo Bambang Yudhoyono.

The Megawati camp alleges widespread fraud in the Wednesday vote, including millions of fake voters, despite an early official count giving Dr Yudhoyono 61.88 per cent of the vote to Ms Megawati's 28.57 per cent.

'It seems that SBY has the compelling urge to be congratulated,' Ms Megawati campaign spokesman Aria Bima told AFP, referring to the president by his initials.

'We're reluctant to congratulate SBY because we're still waiting for the final official results from the electoral commission.'

Ms Megawati's running mate and ex-special forces chief Prabowo Subianto has said the campaign was preparing legal action over alleged fraud, while Ms Megawati has denounced the poll as an exercise in 'pseudo-democracy'.

'We're still counting an accumulation of violations regarding voters being registered twice, children on the electoral rolls and vote counting irregularities. We'll report this to the supervisory body,' Mr Bima said.

Despite the allegations, most political analysts say the election was largely free and fair and that Dr Yudhoyono's apparent victory was so big as to make any voter list irregularities irrelevant.

Economic and political stability during the president's four-and-a-half year term - as well as well-timed direct cash payments to the poor and fuel price cuts - are generally credited with cementing the president's popularity.

Dr Yudhoyono himself has avoided explicitly claiming victory in the polls, but made a show to the media on Thursday of announcing a congratulatory telephone call from his other poll rival, incumbent Vice-President Jusuf Kalla.

He has also said he has received calls of congratulations from world leaders including Malaysian Prime Minister Najib Razak and Australian Prime Minister Kevin Rudd. -- AFP
