In the February 2013 general election, the NNP won all 15 parliamentary seats. After this resounding victory, Mitchell was sworn in as Prime Minister on 20 February 2013. Looking ahead to the next election, Mitchell predicted that his party could win all 15 seats in parliament for a third time. Mitchell and his New National Party created history by retaining all 15 seats in the Grenada General Election of 13 March 2018. It is the first time any political party regionally or otherwise has achieved such a feat.
