  Based on a campaign of change against the PNM, the UNC was successful in the 2010 general election, and Persad-Bissessar was appointed as the first-ever female Prime Minister of Trinidad and Tobago. The UNC won a majority of 21 seats. Their coalition controlled 29 seats in total; the Congress of the People won 6 seats and the Tobago Organization of the People won Tobago's only 2 seats.
  
  After the election, the coalition showed signs of weakening. The Movement for Social Justice, which did not win any seats in the election, left the coalition due to discontent with the running of the government. The Tobago Organization of the People failed to win a single seat in the 2013 Tobago House of Assembly elections.
  
  During 2013, the UNC lost 2 seats in by-elections in St. Joseph and Chaguanas West.
