Uganda opposition coalition collapses Uganda's opposition coalition says it has failed to agree a joint presidential candidate to challenge veteran leader Yoweri Museveni. The Democratic Alliance (TDA) had been expected to select either Kizza Besigye, leader of the Forum for Democratic Change (FDC) party and a three-time challenger, or ex-prime minister Amama Mbabazi. Both men will now run against Museveni - and each other. FILE IMAGES.
