Joseph Kabila, the 55-year-old former president of the Democratic Republic of Congo, has added another entry to his résumé: rebel leader. Because apparently, after 18 years running the country, he missed the thrill of toppling governments - especially the one he handed power to. In a plot twist that would make a soap opera writer blush, Kabila now leads the Front for the Refoundation of the Nation (FRN), an alliance that includes the M23 rebels, who last year seized Goma and Bukavu in eastern DR Congo. The man he's sworn to topple? Félix Tshisekedi, the very successor he helped install. And one of the rebel groups he once fought as president is now his ally. Politics in DR Congo: where alliances are ephemeral and irony is eternal.

When Kabila was named leader of the FRN earlier this month, it confirmed what many Congolese had long suspected: the former president was working with the M23. The confirmation sent shockwaves through a country two-thirds the size of western Europe, rich in gold, diamonds, and the minerals that power everything from mobile phones to EV batteries. For Kabila, this alliance offers a possible route back to power. For the M23, it brings the experience and networks of a former head of state to a movement whose military advances have yet to translate into broad national legitimacy. But ousting Tshisekedi is far from certain.

Policy analyst Henry-Pacifique Mayala told the BBC that Kabila had few options left. "He actually was left with no other choice," Mayala said. Facing a death sentence after being convicted in absentia of treason, plus US sanctions over his alleged support for the M23, Kabila may have sought assurances that the partnership could serve his interests. "I'm not sure that he is making this huge leap in the dark without having received considerable assurance," Mayala added, noting that the M23's military strength could give Kabila leverage in future negotiations with the Congolese government.

Kabila's involvement also raises questions about whether the conflict could spread beyond the east. The M23's territorial gains have been concentrated in the eastern provinces, some 1,500km (1,000 miles) from the capital, Kinshasa. Kabila's political networks could give the rebellion a broader reach, but that doesn't necessarily mean it can extend its military campaign across the country. And it's unclear how far Kabila's national reach extends. While in power - after being named following the mysterious assassination of his father Laurent in 2001 - he was often seen as something of an outsider in Kinshasa. He was far more at home speaking Swahili, the lingua franca of eastern DR Congo and east Africa, rather than the Lingala spoken in Kinshasa.

His father's rebel group actually walked across the country to Kinshasa, also starting in the east, over seven months, before eventually seizing power in May 1996 and ousting long-time ruler Mobutu Sese Seko, who had governed the country as his own personal property for more than 30 years. There's little suggestion that Joseph Kabila's FRN would try to repeat that feat, but earlier this week, he likened Tshisekedi to Mobutu. "You have a tyrant who wants to impose and dictate what he thinks is right and not necessarily follow the constitution, which is the supreme law of the land," he told Conspiracy Trackers Great Lakes (CTGL), a pro-M23 research group. Kabila accused the government of using the death penalty - ending the moratorium introduced during his own presidency - to intimidate civilians, politicians, military members, and himself. He framed his confrontation with Tshisekedi as a fight against authoritarianism, invoking Section 64 of the constitution, which calls on citizens to resist anyone who seizes power or exercises it in violation of constitutional provisions.

Tshisekedi is rumoured to be planning to change the constitution to allow him to seek a third term, with the C64 coalition of opposition parties named after that same section of the constitution, campaigning against such a move. But in a sign that Kabila may not get everything his own way, the C64 coalition this week refused to back his rebellion, saying that Congo's multiple security crises cannot be resolved by military means alone. Instead, it announced plans to seek direct talks with both Tshisekedi and Kabila in pursuit of what it called a "genuine and inclusive national dialogue."

Richard Moncrieff, a Great Lakes analyst with the International Crisis Group think-tank, said President Tshisekedi retains substantial advantages. "Tshisekedi has strong American backing. He has a lot of money. And he generally controls the political system and, as far as we can see, the military system," Moncrieff said. In his first public reaction to Kabila being named FRN leader, Tshisekedi was damning: "In my view, it's simply proof that he has never loved this country, and even less its inhabitants," he said last week.

And yet Kabila is widely believed to have helped ensure that Tshisekedi succeeded him, rather than Martin Fayulu, who was the true winner of the 2018 elections, according to leaked results provided by the Catholic Church, which had observers around the country. Indeed, the former head of the electoral commission who announced Tshisekedi as the winner, Corneille Nangaa, has said as much. Now one of Kabila's deputies in the FRN, he claimed that Kabila and Tshisekedi had reached a political agreement before the final election results were announced. "I can confirm that I helped draft the deal," Nangaa told France 24 in September 2023. "Tshisekedi is a liar. He knows there was an agreement and he knows what was contained in the deal." Tshisekedi has maintained that he won the election legitimately.

After the disputed election, Kabila and Tshisekedi entered a power-sharing arrangement that allowed Kabila's coalition to retain control of parliament even after Tshisekedi took office in January 2019. The arrangement unravelled in December 2020, when Tshisekedi moved to break Kabila's parliamentary dominance and build his own majority. The former allies became rivals, and Kabila went into self-imposed exile in South Africa. From exile, Kabila's criticism of Tshisekedi grew louder. He returned to DR Congo in 2025 and appeared in rebel-held Goma. In September that year, a military court sentenced him to death in absentia on charges including treason and financing violence in eastern Congo. At the time, he rejected the accusations.

Yet another intriguing sub-plot to the announcement is Kabila's relationship with Rwanda's President Paul Kagame. In the early years of his presidency, ties were strained between DR Congo and Rwanda, which accused its giant neighbour of not doing enough to remove ethnic Hutu militias involved in the 1994 Rwandan genocide from its territory. Their presence in what is now DR Congo has been used to justify Rwanda's repeated military involvement in its giant neighbour, going back to its backing of Laurent Kabila's rebellion. The M23 was formed in 2012, vowing to stand up for the rights of ethnic Tutsis and to protect them against these militias, but also battling the Congolese army, under the control of Joseph Kabila. From the start Rwanda was accused of backing them. It has always denied these allegations, as it still does despite overwhelming evidence. However, relations later improved and Kabila's government worked with Rwanda against the Hutu militias.

Alex Adams, Africa programme director at the European Council on Foreign Relations, said Kabila's appointment as rebel leader could bring his interests into alignment with those of Rwanda's president, even though their objectives differ. "Kabila wants to recover political influence nationally, while Kagame is primarily concerned with Rwanda's security and strategic position in eastern Congo. This is an alignment of convenience rather than a partnership built on deep trust," he said. Policy analyst Mayala said Kabila's involvement could help Rwanda counter accusations that it was interfering in Congo's internal affairs. "This is a former president. It's finally a Congolese rebellion," he said.

Even before the announcement of Kabila as the rebellion's leader, fighting was continuing despite a peace accord overseen by Donald Trump last year. Part of that deal saw the US sign an agreement to extract DR Congo's mineral wealth and the US has since seemed to side with Tshisekedi by imposing sanctions on various Rwandan officials and bodies, accusing them of prolonging the violence. Elections are scheduled for 2028, but Tshisekedi has warned that fighting in the east could delay voting. Against this backdrop, Kabila has questioned whether elections alone can resolve the country's political crisis. "Does Congo need elections or a revolution?" he asked, arguing that lasting peace required a fundamental overhaul of the country's executive and legislature.

International security analyst Ovigwe Eguegu argues that Kabila is banking on military force to regain political influence, while Tshisekedi seems to be trying to extend his time in office beyond what the constitution allows. "It looks like the Congolese people are going to lose either way, because neither of these two sides present a credible economic transformation plan for both the eastern Congo and the entirety of the country," Eguegu said.
