Zambia’s main opposition leader, Brian Mundubile, has been questioned by police over alleged treason following a disputed presidential election that saw President Hakainde Hichilema secure a second term.
Mundubile, who reportedly won about 38 percent of the vote, and his running mate, Makebi Zulu, were taken into police custody on Thursday. Police said they were questioned in connection with an alleged treason offence and that “warn and caution” statements had been recorded.
The questioning comes amid growing tensions following the August 13 presidential election. Mundubile had announced plans to challenge Hichilema’s victory in court, but Zambia’s judiciary was closed on Monday — the final day for filing an election petition — with authorities citing security concerns.
Under Zambia’s Constitution, presidential election petitions must be filed within seven days of the results being declared. A successful filing would automatically suspend the president-elect’s inauguration until the court process is completed.
However, the Constitutional Court said it had not received a valid petition challenging the election result. Chief Justice Mumba Malila said he had received a petition through his private email, but described it as “highly irregular” before referring it to the Constitutional Court.
The closure of the courts has drawn criticism from rights groups. Human Rights Watch said the decision was a setback for the rule of law, transparency and due process in Zambia.
The political tensions have also been accompanied by a security crackdown. Former cabinet minister Mutotwe Kafwaya was shot and killed during a police operation at Mundubile’s residence, where 11 people were arrested. Police accused those arrested of involvement in alleged insurrection or militia activities, allegations Mundubile has denied.
Despite the controversy, Hichilema is expected to be sworn in for a second term after winning about 60 percent of the vote.
The developments have raised concerns among opposition groups and civil society organisations about the state of democracy and political freedoms in Zambia.
