Uganda’s President Yoweri Museveni is seeking a seventh term after ruling the country since taking power in 1986.
More than three-quarters of Ugandans are under 40 and have never known another leader.
Museveni previously criticised African leaders who cling to power but later oversaw the removal of term and age limits.
Critics say he has maintained control by weakening institutions, restricting media and suppressing opposition.
Opposition figures including Kizza Besigye and Bobi Wine have faced arrests, prosecutions and violent crackdowns.
We don’t believe in term limits.
Museveni said previously, defending constitutional changes.
Security forces have been accused by the UN of using live ammunition and abductions against protesters.
Museveni’s supporters credit him with stability, economic growth and making Uganda Africa’s largest refugee host.
The president has promoted foreign investment and pledged to make Uganda a middle-income country by 2040.
Critics fear Uganda is becoming a family dynasty, with Museveni’s wife and son holding senior state roles.
Museveni insists he remains fit to lead and urged voters to back his ruling party ahead of the election.
