Incumbent Prime Minister Portia Simpson Miller, 70, is being challenged by the Jamaica Labour Party under Andrew Holness, 43, which is promising tax cuts and new jobs.

Austerity measures introduced by Ms Simpson Miller have led to growth.

Inflation fell to a 48-year low during her time in office.

Last year GDP grew by 1.3%, according to World Bank figures.

Top candidates

• Portia Simpson Miller became Jamaica's first female head of government when she took over from PJ Patterson in 2006
• She lost the election in 2007 to Bruce Golding of the Jamaica Labour Party
• Andrew Holness has also been prime minister before, taking over from Mr Golding in 2011
• He served for two months before being defeated by Ms Miller Simpson in the December 2011 election

But with youth unemployment at 38%, Mr Holness' plan to increase spending to boost jobs has attracted voters.

Mr Holness says he wants to turn Jamaica into "the Silicon Valley of the Caribbean".

In 2013, the country agreed to a four-year International Monetary Fund (IMF) loan package in exchange for swapping its debt.

Ms Simpson Miller's party, the People's National Party (PNP), prides itself on "bringing back the country from the verge of economic collapse" but the package expires next year.

Stampede

The final days of campaigning were marred by violent incidents.

Two people were shot dead and several more injured during a campaign event on 7 February as Mr Holness was addressing supporters.

On Tuesday, shots were also fired during a PNP rally triggering a stampede in which dozens of people were hurt.

However, the numbers of those hurt or killed have been much lower than in previous election campaigns.

Sixty-three parliamentary seats are up for election.

The party that wins a majority of those seats will form the government for a five-year term.

There are 1.8 million registered voters.

Members of the police and military as well as election workers cast their votes earlier, on Monday.
