United Democratic Alliance
The UDA was formed on 1 March 2006 by the United Party for National Development (UPND), the United National Independence Party (UNIP) and the Forum for Democracy and Development (FDD), which between them had won 74 of the 150 elected seats in the National Assembly in the 2001 elections. Anderson Mazoka, who had finished as runner-up in the presidential elections, was the alliance's leader until his death in May 2006. He was succeeded by Hakainde Hichilema, also of the UPND.
In the 2006 elections Hichilema finished third out of the five presidential candidates with 25% of the vote. In the National Assembly elections the party received 23% of the vote, winning 26 seats.
The three parties contested the 2011 elections separately.
