Alvaro Colom has been sworn in as Guatemala's first leftist president in more than 50 years, promising to fight poverty in a nation where half the people live on less than $1 a day.
Colom took office on Monday in a ceremony attended by world leaders, including presidents of Venezuela and Colombia.
"Today is the beginning of privileges for the poor, the beginning of privileges for those without opportunities," Colom, 56, said after receiving the presidential sash to the tune of traditional Mayan music.
Despite his ideology, Guatemala's new leader said he doesn't want to be identified with other leftist governments in Latin America, including that of Hugo Chavez, the Venezuelan president.
'Independent path'
Colom has said each country must "find its own path", and that he won't accept Venezuela's offer of oil for preferential terms until he has consulted with his country's business elite.
The ceremony was attended by Mayan leaders, some wearing colourful embroidered blouses and skirts. Also taking office on Monday was Rafael Espada, the vice-president.
"We are going to fight for the unity of the country, for the harmony with our indigenous people," Colom said.
Colom, an industrial engineer, has promised a broad social agenda that includes building schools and medical centres, creating jobs, and bringing security to a country where gangs behead victims and drug traffickers control much of the police forces.
But even Colom has recognised his job won't be easy. Half of Guatemala's 13 million people live on less than $1 a day, and discrimination against the ethnic Mayan majority is rampant.
