Ms. Simpson Miller became the first female prime minister in 2006, but lost power after 18 months in office. During her inaugural speech she said she hoped to cut Jamaica's 13 percent unemployment rate. The new prime minister also said slashing the nation's nearly $19 billion debt burden was a priority.
