The son of Uganda’s president, a lieutenant general, announced his retirement from the military on Tuesday, paving the way for a possible presidential bid in 2026.

According to critics of President Yoweri Museveni, Muhoozi Kainerugaba, who has served in the military for over 20 years, was pushed up the ranks by his father. Many Ugandans believe Kainerugaba is being groomed to be Museveni’s successor.

“After 28 years of service in my magnificent military, the best military in the world,” Kainerugaba wrote on Twitter on Tuesday, without explaining why he was retiring.

Museveni, 77, who has controlled the east African country since 1986, has frequently refuted allegations that he wants to give over power to his son, though Kainerugaba’s supporters argue he has the same right as any other citizen to run for president.
