The Botswana government on Tuesday dismissed as "outrageous and unfortunate" allegations made by ex-president Ian Khama accusing his successor of undermining democracy in one of Africa's most stable nations.
Khama, 70, made damning allegations in a recent interview claiming his handpicked successor Mokgweetsi Masisi had "totally undermined democracy, human rights, the rule of law".
But the government denied the "unfounded" accusations, describing them in a statement as "outrageous and unfortunate, politically motivated and with the sole intention of tarnishing the good image" of Botswana and its government
Khama led Africa's top diamond producing nation for a decade until 2018, before handing the reigns to Masisi, who had been his deputy.
"Botswana is a democratically governed nation-state that keenly respects and observes the rule of law and ethics of good governance underpinned by adherence to a culture of human rights," said the government.
Khama, who has been based in South Africa since November 2021, drew parallels between Masisi and ex-American president Donald Trump.
Government said it concluded Khama's motives coming a year before general elections due in 2024, were "questionable".
In 2018 Khama dramatically quit the long-ruling Botswana Democratic Party, which had been co-founded by his father Seretse Khama, Botswana's first president, and went on to back an opposition party.
He has vowed to bring the opposition parties into an electoral alliance to remove Masisi through the ballot box in next year's polls.
The former senior military officer and head of state said he had intelligence information on plans to arrest and poison him if he returned home.
Gaborone rubbished the claim.
