Ousted Maldivian President Mohammad Nasheed is confident of a "landslide" victory in the upcoming presidential elections, which will be held again later this month after the Supreme Court annulled the previous round, an official said here on Wednesday.

Nasheed, candidate of Maldivian Democratic Party (MDP), won 45. 45 percent of the vote in the first round in September.

MDP spokesman and former Foreign Minister Ahmed Naseem insisted that the elections should take place before 20 October as announced by the country's Supreme Court and stressed that the Maldivian people are not interested in turning back from democracy.

The Maldives saw 30-year autocratic leader ousted from power by Nasheed in 2008.

However Nasheed himself was removed from power in February 2012 in what he alleged was a coup.

"No one wants a fail state... it will be a fail state if we do not elect a president by 11 November," he told reporters shortly after the Maldivian Supreme Court ordered fresh polling.

"We have tasted democracy for 3 years. The people have tasted democracy we don't want to go back to 30 years of dictatorship," he added.

The Maldives Supreme Court annulled the results of last month's presidential elections and ordered a fresh ballot within the next 13 days on Monday night.

The news came amidst prolonged political unrest in the Indian Ocean islands.

The court ordered that if no candidate secured an absolute majority in the fresh elections to be held before October 20, a runoff election should be held before November 4.

The Supreme Court in its verdict noted that a total of 5,623 irregularities were found in the electoral list used for the first round of voting.

The Supreme Court order came days after a television station supportive of Nasheed was set on fire sparking call from the international community for a transparent investigation.

A new president must be sworn in by 11 November according to the Constitution.
