After decades of intense divisions, Sudan's political opposition united recently to form a powerful three-pronged bloc that became part of the protest wave which ousted autocrat Omar al-Bashir last week.
During Bashir's politically repressive three-decade rule, Sudan had around 100 political parties. They ranged from Islamists to leftists and ran the gamut from ardent critics to regime loyalists.
A military transitional council is now set to rule the country for the next two years. Veteran journalist Mahjoub Mohamed Saleh, 91, mapped out the political trajectories of the burgeoning opposition movement for AFP.
"The opposition in Sudan now is made up of the (Paris-based) Nidaa Sudan, the National Consensus Forces and the Sudanese Professionals Association," said Saleh, who was imprisoned several times during Bashir's reign.
Collectively, the tripartite bloc is known as the Alliance for Freedom and Change. Nidaa Sudan includes the Umma Party, the Sudanese Congress Party as well as armed movements such as the Sudan People's Liberation Movement.
The Umma Party is led by Oxford-educated Sadiq al-Mahdi, who was prime minister twice during the 1960s and 1980s and was ousted by Bashir's 1989 coup. He returned to Sudan this year after a year of self-imposed exile in Cairo.

Meanwhile, the "more radical" Sudanese Communist Party and the Baath Party alongside other leftist gatherings form the National Consensus Forces.
Lastly, the Sudanese Professionals Association (SPA) is comprised of small political cadres mostly staffed by young, urban people counting academics, doctors and engineers among their ranks.
They have been the driving force behind mobilising thousands of demonstrators through their savvy and active social media usage to protest against Bashir since December 18.
The SPA has called on the transitional military council to immediately "hand over power" to a civilian administration and urged demonstrators to continue with their sit-ins.
Protesters have been camped for several weeks in front of important government buildings throughout the country.
Saleh says the opposition bloc has been the most consistent and well-organised in agitating for tangible political change. "For four months, these people were not afraid to put their bodies on the line," he said. Over 30 protesters have been killed in clashes with security forces since the uprising erupted.
The bloc has urged the forthcoming transitional government to arrest Bashir and a coterie of political elite figures who have been in power since the 1989 coup. These include the powerful security and intelligence chiefs and leaders of Bashir's National Congress Party.
"All the various parties that make up the opposition are now going to unite, sort out their differences and learn from their previous mistakes at this crucial time," he added.
"But when things return to their natural state, political squabbles and factional in-fighting will ultimately emerge."
