President: Irfaan Ali
The hotly-disputed March 2020 election was eventually resolved in favour of opposition candidate Irfaan Ali, who became the country's first Muslim president in August.
A former housing and tourism minister in People's Progressive Party governments, Mr Ali beat the incumbent president, David Granger of the People's National Congress, after a full recount amid allegations of government vote-rigging.
A coalition led by the People's Progressive Party also won a narrow majority in the simultaneous parliamentary election.
