Keypoints:
- Mundubile and Zulu detained over alleged treason
- Probe follows Zambia’s disputed presidential election
- Court petition controversy deepens political tensions
ZAMBIA’S bitter post-election dispute has escalated dramatically after opposition leader Brian Mundubile and his running mate Makebi Zulu were detained by police investigating an alleged treason offence, deepening concerns over the political fallout from President Hakainde Hichilema’s re-election.
The arrests move a confrontation that began at the ballot box into Zambia’s criminal justice system at a particularly sensitive moment. Mundubile disputes the August 13 presidential result, while controversy continues over the closure of the country’s courts on the final day available for filing an election challenge.
Reuters reported that the Zambia Police Service recorded ‘warn and caution’ statements from Mundubile and Zulu in connection with alleged treason under Section 43(1) of the Penal Code. Both remained in custody while investigations continued. Police had not publicly detailed the specific conduct forming the basis of the allegation or confirmed formal charges.
The distinction is crucial. A police investigation and warn-and-caution statement do not amount to a conviction — or necessarily a formal criminal charge.
Treason probe follows disputed vote
Mundubile, who challenged Hichilema in the August 13 presidential election, surrendered alongside Zulu after the pair had sought refuge at a United Nations facility in Lusaka.
The UN said Zambia’s government had given assurances that the two opposition politicians would receive due process under the law.
Hichilema was declared the winner with about 60 percent of the vote, while Mundubile secured roughly 38 percent, according to official results.
Mundubile rejected the outcome and alleged electoral irregularities. Hichilema has denied claims that his victory was fraudulent. The dispute followed an election in which counting was temporarily suspended after attacks on polling officials and the theft of ballot papers at some locations.
Africa Briefing previously reported on Mundubile’s planned challenge to Zambia’s election result as political tensions intensified following the vote.
Raid casts shadow over detention
The treason investigation cannot be separated from the security operation that preceded Mundubile’s detention.
Security forces raided Mundubile’s home shortly after the election and arrested 11 people. Authorities alleged that weapons and military equipment were discovered and accused those detained of involvement in activities posing a threat to national security.
Former cabinet minister Mutotwe Kafwaya was fatally shot during the operation.
The circumstances of his death remain disputed. Authorities said security officers came under fire and responded, while Mundubile has rejected that account and denied allegations that opposition figures were preparing an insurgency.
Amnesty International described Kafwaya’s killing as deeply alarming, while the UN human rights office has raised concerns about the detention of opposition figures around the election period.
Those competing accounts make the evidence eventually presented by investigators particularly important.
Court closure fuels controversy
The treason probe has also unfolded against an extraordinary legal dispute.
Zambia’s top courts, including the Constitutional Court, were closed on August 24 — the final day available for challenging the presidential election result.
A judiciary memorandum cited security concerns for the closures. Police were deployed around court premises as Mundubile’s allies sought to pursue an electoral challenge.
The timing generated criticism from legal and human rights groups and raised questions about whether the opposition had been given an effective opportunity to seek constitutional redress.
Africa Briefing reported that Zambia’s court shutdown coincided with the election petition deadline.
The Judiciary later said no presidential petition had been formally filed at the Constitutional Court registry by the deadline.
But the issue has not disappeared.
Chief Justice Mumba Malila confirmed receiving documents described as ‘the people’s presidential petition’ through his private email address. He called that method of submitting official court documents ‘highly irregular’, but referred the material to the Constitutional Court to consider the question of filing.
That leaves the legal status of the emailed documents for the court to determine.
Treason carries life imprisonment
The stakes of the criminal investigation are exceptionally high.
Section 43 of Zambia’s Penal Code states that a person convicted of treason is liable to life imprisonment.
The offence includes preparing or attempting by unlawful means to overthrow the legally established government, attempting through force to alter government law or policy, and certain other acts involving the forcible usurpation of state power.
Zambia removed the death penalty from the provision in 2022.
Police have not yet publicly explained which alleged actions by Mundubile and Zulu they believe fall within those provisions.
Until they do, descriptions of the case must remain precisely framed as allegations under investigation.
Hichilema’s own treason history
The episode carries striking historical resonance for Hichilema.
In 2017, when he was Zambia’s main opposition leader, Hichilema himself was arrested and charged with treason under President Edgar Lungu’s government after a confrontation involving the presidential motorcade.
He remained imprisoned for about four months before prosecutors discontinued the case.
Reuters reported at the time that the release followed a Commonwealth-backed dialogue process intended to ease political tensions after another fiercely disputed election.
Nine years later, Hichilema is president and his principal electoral challenger is facing investigation under the same category of offence.
The parallel does not prove political interference in the current case. But it inevitably places the conduct of Zambia’s police, prosecutors and courts under intense scrutiny.
Zambia’s democratic standing tested
Zambia has traditionally been regarded as one of Southern Africa’s more competitive electoral democracies, with changes of government achieved through the ballot box since the restoration of multiparty politics.
Hichilema entered the election able to point to major debt restructuring and improving relations with international lenders, but his administration has also faced criticism from civil society organisations over restrictions on political and civic space. He has rejected accusations that enforcing the law against suspected offenders amounts to suppressing opposition voices.
How the Mundubile investigation is handled could therefore have consequences extending far beyond the two men now in custody.
The immediate questions are whether police will disclose the evidence behind the treason allegations, whether Mundubile and Zulu will be formally charged or released, and how the Constitutional Court will deal with the disputed election petition documents.
For Zambia, the credibility of those processes may prove decisive in determining whether the aftermath of the 2026 election becomes a contained political dispute — or a deeper test of the institutions that have underpinned the country’s democratic reputation.
