In the elections held on 19 July 1997, the UP presidential candidate Ellen Johnson Sirleaf won 9.58% of the vote. The party won seven of 64 seats in the House of Representatives and three of 26 available in the Senate. While international observers deemed the polls administratively free and transparent, they noted that it had taken place in an atmosphere of intimidation because most voters believed that former rebel leader and National Patriotic Party (NPP) candidate Charles Taylor would return to war if defeated.
Former Vice President Boakai remains the Standard Bearer of the Party and the leading opposition contender for the upcoming 2023 Presidential elections. Hon. Boakai was instrumental in the formation of the Collaborating Political Parties (CPP) that brought together the four largest opposition political parties, the All Liberian Party (ALP), the Alternative National Congress (ANC), the Liberty Party (LP), and the Unity Party (UP) to form an opposition bloc against Pres. Weah's Coalition for Democratic Change (CDC).
The Party is constitutionally led by its chairman, Amin Modad, who was elected in September 2020 with over 62% majority after defeating veteran politician Sen. Conmany Wesseh and others. Modad, a former representative to the World Trade Organization, cited his business background as evidence of his suitability for the role.
