Guyanan President Bharrat Jagdeo was sworn in on Saturday after being re-elected several days ago, according to reports reaching Caracas from Georgetown, the capital of the South American country between Venezuela and Suriname.
At the inauguration ceremony, Jagdeo told other politicians including opposition leaders that as "the president of all of Guyana," he needed to work with them in his new term of five years.
He expressed hope that he could meet the leaders of the political parties in parliament to "hammer out a framework of cooperation."
An ethnic Indian, the 42-year-old president was re-elected with his ruling People's Progressive Party garnering 54.6 percent of the vote in Monday's polling. The party also expanded its majority by two to 36 seats in the 65-member parliament.
Jagdeo has been in power since 1999. He was educated in Russia and became an economist.
He vows to improve governance while cracking down on crime in a country of 750,000 people.
Guyana, a former British colony, remains poor and lacks investment. Besides economic instability and crime like drug trafficking, the re-elected president also faces the challenge of persistent strife between the nation's two main ethnic groups -- those descended from Africans and those whose ancestors came from the Indian subcontinent.
