President Bharrat Jagdeo has won re-election and his ruling People's Progressive Party increased its majority in Guyana's parliament, the elections commission said Thursday.

With all ballots counted from Monday's general election, the PPP had received 183,887 votes, or about 55 percent, and increased its seats in parliament by two to 36, chief elections officer Gocool Bodhoo told a news conference.

The victory meant the PPP, which is dominated by Guyanese of East Indian descent, retains control of parliament and the presidency for a fourth consecutive term.

"We campaigned fair and square and it's reflected in the size of the victory," Jagdeo said. "It's important to know that we won a seat in every geographical constituency in the country, and this says a lot for our policies over the last five years."

Election observers from the Commonwealth Secretariat in London reported minor administrative problems at the polls but said they didn't "undermine the overall integrity and credibility" of the vote.

PNC leader Robert Corbin, who conceded defeat on Wednesday, called for power sharing between racial groups in the country and deplored the election results, which he said "proved to be an ethnic census."

The upstart Alliance for Change, a party that offered itself as an alternative to racially based politics, won five seats with 28,366 votes.

The remaining 9,500 votes were split among seven minor parties, with two winning parliamentary seats. An estimated 69 percent of the country's 492,000 eligible voters cast ballots, Bodhoo said.

"We're very, very satisfied that we have delivered credible elections, there is no doubt about that," he said. "This is the first time, in a long time, we have delivered results so early."

Election observers from the Commonwealth Secretariat in London reported minor administrative problems at the polls but said they didn't "undermine the overall integrity and credibility" of the vote. Observers from the Caribbean Community and the Organization of American States have said they were satisfied with the conduct of the vote.

Jagdeo, a Moscow-trained economist, will be sworn in for a second five-year term on Saturday.

During the campaign, Jagdeo rejected accusations against his party including racial discrimination, corruption and granting timber concessions to drug traffickers that allowed them to build outposts in the interior. He claimed credit for wide infrastructure improvements and a $500 million reduction in Guyana's foreign debt.

The U.S. Embassy has estimated narcotics traffickers earn at least $150 million annually in the country on South America's northern coast, equaling at least 20 percent of its gross domestic product.
