Here's why Buhari cannot resume his duty as Nigeria's president immediately after his return.
President Buhari who touched down at the Kaduna Airport at 7:41 am, was received by top government officials.
Addressing cabinet members and Governors at the Aso Rock Presidential Villa, President Buhari stated that his vice, Professor Yemi Osinbajo would continue to lead Nigeria.
President Buhari's comment immediately began to generate reactions from Nigerians.
Here are three reasons why Buhari cannot resume duties as Nigeria's president following his return to the country:
1. President Buhari needs to formally inform the National Assembly of his return
Before leaving for London, President Buhari wrote to the National Assembly to inform the legislature of his planned vacation to the United Kingdom.
The news of handing over power to his vice, Prof Yemi Osinbajo, was also contained in that letter.
Again, the president wrote to inform the National Assembly of the extension of his stay in the U.K.
Although the National Assembly is aware of the president's return, he still needs to formally notify them.
"That makes his return to work formal, and constitutional," says President Buhari's media aide, Femi Adesina.
2. President Buhari is 'so sick'.
Against the 'hale and hearty' proclamation by the trio of Lai Mohammed, Garba Shehu and Femi Adesina, President Buhari confessed to being sick while addressing members of his cabinet at the Villa.
“I am feeling much better now. There may, however, need to have further follow-ups within some weeks,” President Buhari said.
"I have received the best of treatment I can receive. I couldn’t recall ever being so sick since I was a real young man including the military goings ups and downs,” he added.
3. President Buhari needs more rest
President Buhari told his vice, Osinbajo to continue as acting president while he continues to rest.
“I deliberately came back towards the weekend so that the vice-president will continue and I will continue to rest,” he said.
But Tolu Ogunlesi, Buhari's aide on digital communication has a different interpretation to the President's comment.
