Washington — This week, acting Nigerian President Goodluck Jonathan dissolved his cabinet, further securing his tenuous hold on the country's top post amidst rising unrest in the Niger Delta and flaring religious tensions in the central region of the country.

 
On Wednesday, Goodluck dismissed all of ailing President Umaru Yar'Adua's ministers, effectively allowing the acting president to appoint ministers of his choosing.

Yar'Adua, who has been receiving medical treatment in Saudi Arabia for three months, returned to Nigeria on Feb. 24 amidst a heavy military presence at the airport, but hasn't been seen since.

"[Jonathan] did not give us any reason for the dissolution of the cabinet," said Dora Akunyili, the information minister, in a short statement released on Wednesday.

On Feb. 10, Nigeria's National Assembly voted to make Goodluck the acting president. Since then, Goodluck's aggressive power consolidation has furthered the hopes of many Nigerians hopes that reform is imminent.

"[Jonathan's dissolution of the cabinet] is a signal for many that Goodluck Jonathan is perhaps about to put in place his own men, his own women, his own team," said Al Jazeera's Nigeria correspondent, Yvonne Ndege, on Thursday.

"It was felt by many Nigerians that the cabinet was basically packed to the rafters with Yar'Adua loyalists who weren't doing the job they were supposed to be doing, or rather doing a good enough job," said Ndege.

Questions still remain over who will take on the post of vice president, as well as who will gain the support of the military. With elections due in less than one year, the clock is ticking for Goodluck Jonathan to present a viable path forward.

The military, which holds considerable sway in Nigerian politics, appears to be at odds about the current leadership crisis. John Campbell, who served as U.S. ambassador to Nigeria between 2004 and 2007, wrote in a recent op-ed in the Huffington Post that "the Nigerian military appears as splintered as the rest of the federal government."

Campbell went on to surmise that some elements within the army are staying loyal to Yar'Adua, as neither Jonathan nor the chief of defense staff - the most senior officer in the military - were notified about Yar'Adua's return.

A large number of military personnel greeted Yar'Adua's plane and escorted his ambulance to the presidential palace upon his return from Saudi Arabia.

It is not clear who wields power in the country at this point, or if Yar'Adua's absence becomes permanent, who will take over.
