Union for the Congolese Nation

There were a number of reasons Kamerhe fell out of favor with Joseph Kabila and ultimately left the ruling party to form his own political party. One major issue was Kamerhe's opposition to Kabila's plan to amend the country's constitution to allow him to run for a third term as president. Kamerhe publicly criticized the move, arguing that it violated the principles of democracy and that it would be damaging to the country's stability. This put him at odds with Kabila and his supporters, who were pushing for the constitutional change.[11][12][13][14] Another factor was Kamerhe's concerns about corruption within the ruling party. He accused Kabila's government of engaging in corrupt practices, such as embezzlement of public funds and nepotism, and called for greater transparency and accountability in government. This stance further strained his relationship with Kabila and his allies.[15][16][17] Finally, there were personal factors that contributed to the rift between Kamerhe and Kabila. Some reports suggest that Kamerhe was frustrated by his lack of influence within the ruling party and by Kabila's unwillingness to take his advice on key policy matters. Additionally, there were rumors of a power struggle between Kamerhe and Kabila's inner circle, with some alleging that Kamerhe was seeking to position himself as Kabila's successor.[18][19]

Consequently, Kamerhe fell out with Kabila and left the PPRD on 25 March, 2010, to form the UNC. The UNC quickly gained support in the eastern part of the DRC, where Kamerhe was from and where he had a strong political following.[20]

In the 2011 presidential elections, Kamerhe played a significant role in the campaign of Étienne Tshisekedi, the main opposition candidate who ran against Kabila. Kamerhe ran as an independent candidate under the UNC banner at the time and was appointed as the campaign director for Tshisekedi. Kamerhe was known for his strong public speaking skills and his ability to mobilize crowds during the election campaign. He organized rallies and public events in support of Tshisekedi and the opposition coalition, helping to galvanize popular support against Kabila's government. However, the 2011 election was marred by allegations of voter fraud and irregularities, leading to protests and clashes between opposition supporters and security forces. Kabila was ultimately declared the winner of the election, but the opposition coalition, including Kamerhe and Tshisekedi, rejected the results and called for new elections. After the 2011 election, Kamerhe remained a prominent opposition figure and continued to speak out against Kabila's government.[21][22][23][24][25][26]

In the 2018 elections, Kamerhe ran as the UNC's candidate, proposing a number of policy initiatives, including plans to improve infrastructure, create jobs, and combat corruption. He also advocated for greater transparency in the electoral process, and called for fair and credible elections. However, despite his popularity and efforts to run a strong campaign, he ultimately finished third in the election, with just over 7% of the vote.[27] The election was marred by allegations of fraud and irregularities, with many opposition candidates and observers questioning the results, including Emmanuel Ramazani Shadary and Martin Fayulu. After the election, Kamerhe became a key figure in the opposition movement, and was a vocal critic of President Félix Tshisekedi and his government.[27][28]
