Vincentians will head to the polls in a general election on December 9.
Prime Minister Dr. Ralph Gonsalves who made the announcement last night, said Nomination Day is set for November 20.
The ruling Unity Labour Party (ULP ) will face a challenge from the main opposition New Democratic Party (NDP) headed by Arnhim Eustace, a former Prime Minister, who lost the 2010 general election.
The ULP was swept into office in March 2001 in an early election following political unrest one year earlier. In that poll, voters overwhelming rejected the NDP, which had been in office for 17 years.
The ULP won 56.5 per cent of the votes in the 2001 poll and 12 of the 15 seats in Parliament, compared to 40.9 per cent to the NDP, which took the remaining three seats.
In 2005, the ULP was returned to office by the same number of seats as 2001, and in the 2010 polls, the party captured 53 per cent of the popular votes, 2.4 percentage points than in 2005.
