Uganda`s challengers: The candidates hoping to unseat Museveni
Mbabazi is the most powerful party loyalist to turn on Museveni.
Kampala: Seven candidates are challenging Uganda`s incumbent President Yoweri Museveni, 71, in Thursday`s election, hoping to end his three-decade rule.
Here`s who they are:
Museveni and Kizza Besigye, 59, were once close. They fought together in the bush war to overthrow Milton Obote, during which Besigye served as Museveni`s trusted personal physician.
Later, Besigye married Museveni`s former girlfriend, but the two men eventually became political foes when Besigye broke ranks with the National Resistance Movement (NRM) to make a bid for the presidency in 2001.
This year is his fourth attempt to unseat Museveni with his Forum for Democratic Change (FDC) party, his best performance so far being the 37 percent he won in 2006.
Spurious accusations of treason and rape, frequent arrests and detentions, regular tear-gassings -- both of him and his supporters -- beatings and harassment have not put Besigye off.
But opinion polls have him lagging behind Museveni with at most 32 percent of the vote, insufficient to force a run-off. Another ex-NRM stalwart, Amama Mbabazi, 67, only abandoned the party he helped build after being denied anointment as Museveni`s successor.
The former prime minister and NRM secretary-general took the slight badly after years of loyal service, including helping to mastermind the removal of term limits in 2005 that paved the way for Museveni`s continuing rule.
Mbabazi is the most powerful party loyalist to turn on Museveni and he did so amid grand corruption allegations, which he has denied. Despite his high profile among Uganda`s political elites, his campaign at the head of the Go Forward party has failed to gain momentum countrywide.
Like his fellow leading contenders -- Museveni and Besigye -- Mbabazi hails from south-west Uganda.
