Prime Minister Andrew Holness’s Jamaica Labour Party (JLP) won a resounding victory, with 49 seats in the 63-member House of Representatives. This was up from 32 in 2016. The People's National Party (PNP), led by Mr. Peter Phillips, took the remaining seats. A record 18 women (up from 11) were elected. They included the Prime Minister’s wife, Juliet Holness, who secured a second term. On 7 September, Governor General Patrick Allen swore in Mr. Holness as the Prime Minister for a third term.

On 15 September, the newly elected House of Representatives elected former Speaker Marisa Dalrymple-Philibert as its Speaker, and Juliet Holness as its Deputy Speaker. It is the first time in the Jamaican Parliament’s history that the Speaker and Deputy Speaker have both been women. The Senate (a 21-member appointed chamber renewed at the same time as the House of Representatives) re-elected Mr. Tom Tavares Finson as its President.

The elections had been due between February and June 2021 but were moved to September 2020. Prime Minister Holness stated that the rise in COVID-19 cases and the devastating effects of the pandemic on employment in the country made it necessary that he “seek another mandate from the people”. During election campaigning, the JLP promised more housing for civil servants and young Jamaicans, the expansion of broadband in public schools and the building of a national broadband infrastructure. The elections were held amid the COVID-19 pandemic and recorded a low turnout. Only 37.85 per cent of some 1.9 million registered voters turned out at the polls, down from 48.37 per cent in 2016.
