The party was established on 14 May 2010 by independent MP
Charles Milupi. As he had changed party affiliation, Milupi was required to stand down as an MP, resulting in
a by-election in which he was re-elected, retaining the seat until the term finished in 2011. He was the party's presidential candidate for the
2011 general elections; he finished fourth in a field of ten candidates with 0.9% of the vote. In the elections to the
National Assembly the party received 1.2% of the vote, winning a single seat; its candidate
Mwambwa Imenda won Milupi's former
Luena constituency. In 2018, the ADD was one of 10 political parties that decided to form the
Opposition Alliance, with ADD president Charles Milupi as the chairperson of the alliance. In February 2021, 5 and a half months before the
2021 general election, the Opposition Alliance was rebranded as the
UPND Alliance and Milupi remained as the chairperson of the alliance. The alliance members decided to endorse
Hakainde Hichilema of the
UPND as their sole presidential candidate. After the UPND won that election in August 2021, Charles Milupi was appointed as the
Minister of Infrastructure, Housing and Urban Development the following month and is therefore a nominated a member of parliament. Ahead of the
2026 general election, Charles Milupi, as the UPND Alliance chairperson, among other alliance members endorsed Hichilema for re-election and therefore the ADD would not participate in that election. ==References==
