[10] Bello Bouba announced the formation of a new party, the National Union for Democracy and Progress in Cameroon (UNDPC), in Paris on May 25, 1990.
[10] Bello Bouba placed third in the election, held on October 11, 1992, behind Biya and Social Democratic Front (SDF) candidate John Fru Ndi,[14] receiving 19.22% of the vote.
[15] He and Fru Ndi disputed the official results which proclaimed Biya the winner[14] and they unsuccessfully sought to have the election annulled by the Supreme Court due to alleged fraud.
This faction then became the National Alliance for Democracy and Progress (ANDP), a new party featuring a slight alteration of the UNDP's name.
[22] Although Bello Bouba was re-elected to the National Assembly in the May 1997 parliamentary election,[4] the UNDP performed poorly, losing many of its seats.
[21] The UNDP then participated in the opposition boycott of the October 1997 presidential election;[21][23] according to Bello Bouba, "there is absolutely no political will on the part of the ruling party to move towards peaceful development ... there is no universal suffrage in a country in which half of the voters are prevented from exercising their right to vote.
"[21] Following the election, in which Biya faced no serious competition, Bello Bouba accepted an appointment to the government as Minister of State for Industrial and Commercial Development in December 1997.
[21] In the 2002 parliamentary election, Bello Bouba was again a UNDP candidate in Benoué West constituency, but this time he was defeated.
[24][25] The UNDP won only one seat in that election, and Bello Bouba described it as a "farce", alleging that low voter registration was used to rig the election in favor of the ruling Cameroon People's Democratic Movement (RDPC); some party members, however, reportedly attributed the UNDP's poor performance to disapproval of Bello Bouba's cooperation with the RDPC in the government.
[30] As a presidential candidate, Bello Bouba—who had a limited base of support that was largely confined to the north—was considered to have no serious chance of winning the 2011 election.
