"We're not going to stand by and allow people to use criminals to decide the future of the Jamaican people," said the 61-year-old whose party is seeking to extend its nearly 20 years in power.
 
Her party's general-secretary, Danny Buchanan, also alleged that some opposition candidates held US citizenship, which he said would be illegal for a member of parliament under Jamaican law.
 
But a statement from the Washington-based Organisation of American States said voters could find their names on the rolls "almost without exception" and praised Jamaica for holding the vote in a "professional and transparent manner".
 
The final count typically takes about two days as election officers in each of the 60 precincts review the ballots, according to Jamaica's Electoral Commission.
 
Simpson Miller, the country's first woman prime minister, was once wildly popular but saw her support wane amid complaints she responded poorly to Hurricane Dean two weeks ago and a perception that she did not fare well in a debate with Bruce Golding, the Labour party leader.
