Portia Simpson Miller, Jamaica’s first female prime minister led her party to a landslide victory against the ruling opposition, the Associated Press reports. Mrs. Simpson Miller, representing the People’s National Party, had served a short stint as the country’s leader before the Labour Party won control of the government in 2007. This time around, her party won 42 seats of the 63-seat parliament, while Labour captured just 21. The ruling party’s loss may be due in part to former prime minister Robert Golding’s handling of notorious drug lord Christopher Coke. Following a U.S. extradition request, Golding authorized an American firm to lobby against the request in Washington. Later, Golding ordered an offensive against Coke’s headquarters, causing violent clashes between Coke supporters and government forces. The results were announced late Tuesday after days of recounting. Barely half of Jamaica’s eligible voters cast ballots. Simpson Miller will be sworn in Thursday.
