New prime minister sworn in after sweep in Antigua June 14, 2014 01:25 GMT ST. JOHN'S, ANTIGUA (AP) -- A new prime minister has been sworn into office in Antigua following a sweep of parliamentary elections by the country's Labor Party. Gaston Browne is the new prime minister of the two-island nation of Antigua and Barbuda. He is a former banker and at 47 is the youngest prime minister in the country's history. Browne was sworn in Friday after his Labor Party took 14 of 17 seats in Parliament. Ousted Prime Minister Baldwin Spencer barely held onto his own seat as his United Progressive Party was swept out after 10 years in power. The Organization of American States said its observers found the election to be well-run but said there were long lines as about 90 percent of registered voters cast ballots.
