Sandwiched between Venezuela and Suriname, the former British colony of Guyana is the only English-speaking country in South America.
Since independence from the UK in 1966, Guyana has seen fierce political rivalry between the two main ethnically-based parties.
Most of the country is covered in tropical rainforest and, despite having rich reserves of bauxite, gold and timber, it has traditionally struggled to overcome poverty and attract investment to bolster its economy.
Guyana's economy has been undergoing a transformation since the discovery of crude oil in 2015 and commercial drilling in 2019. A century-old border dispute with Venezuela has revived after this discovery of major offshore oil reserves.

A coalition led by the People's Progressive Party also won a narrow majority in the simultaneous parliamentary election.
President Ali took over not long after the US oil giant Exxon made one of the world's biggest discoveries of oil in deep waters off Guyana's coast, which could change the country's economic prospects dramatically.
The constitution guarantees free speech, although officials are apt to resort to defamation laws, says Reporters Without Borders.
A bill passed in 2017 was criticised for requiring private broadcasters to carry a daily quota of government-chosen output.
