Ahead of the
2016 general election, Saboi Imboela was a member of the
United Party for National Development and wanted to stand as their parliamentary candidate in
Kafue constituency. However, the party adopted a different person to stand at the election in Kafue. Imboela then joined the
National Democratic Congress (NDC) in December 2017 and was selected to be the NDC's candidate for the Mayor of
Lusaka by-election to be held on 26 July 2018, where she finished 4th in a field of 8 candidates. After that, she was appointed spokesperson of the party in April 2019. In April 2021, the NDC had split into two factions due to a leadership dispute. One of the factions was led by
Chishimba Kambwili while the other was led by
Josephs Akafumba and Imboela was appointed as the vice-president of the Kambwili-led NDC faction at a convention. Within a short time, Kambwili had left the NDC in order to campaign for his former party (the
Patriotic Front) ahead of the
2021 general election and so, Imboela took up the position of acting president for her faction of the NDC. In early 2024, Imboela's faction of the National Democratic Congress was one of the founding members of the United Kwacha Alliance (UKA), an alliance of political parties in Zambia. In November 2025, the president of the other faction of the NDC,
Joseph Kasonde, had left the NDC in order to join the Citizens First party. During his resignation from the party, he handed over the party rights to the faction of Saboi Imboela, thereby rendering that the NDC no-longer has two factions. Imboela would now be legally regarded as the president of the party going forward. On 29 April 2026, the NDC joined the Revamp for Development Change (RDC) and the Citizens First (CF) party to form the CF Orange Alliance, with Imboela among others endorsing
Harry Kalaba of the CF for presidency at the
2026 general election, indicating that the NDC will not field its own presidential candidate. ==Personal life==
