Maiga, who leads the M5-RFP opposition coalition, will become prime minister in an interim government of 25 ministers. The country is expected to hold elections next year.
Mali saw its second coup since August 2020, last week. Led by Vice President Assimi Goita, who was named transitional president, the coup removed President Bah Ndaw and Prime Minister Moctar Ouane from office after accusing them of breaking transition rules.
Another coup in 2012 led to the rise of an Islamist insurgency in the country's north, prompting France to send troops. President Emmanuel Macron threatened to pull troops out of France's former colony if the Islamist takeover repeats itself.
