Nigerian President Muhammadu Buhari is to proceed to London on Sunday night for follow-up medical consultation with his doctors, a statement said.
ABUJA May 9 Nigeria's upper house of parliament aims to consider the government's 2017 budget on Thursday, the Senate president said, and could approve the spending plan the same day in the next stage of its marathon passage into law.
The duration of Buhari's absence will be determined by doctors, Adesina said.
AIED said: "We are extremely saddened with the content of President Buhari's letter where he neglected tradition and voice of sanity to dance to the tune of political vampires by importing a lexicon alien to our constitution".
When you tell us that the Vice President can not be Acting President even though the President is critically sick and on indefinite medical leave in a foreign country you are playing with fire.
He said this while receiving a delegation from Borno which came to thank President Muhammadu Buhari for the recent release of 82 Chibok girls from the Boko Haram captivity.
The President, according to a statement by his Special Adviser on Media and Publicity, Femi Adesina, has also notified the National Assembly of the development.
The Senate President subsequently ruled Senator Ohuabunwa out of order.
Buhari on his last return admitted to the media that he had never been so sick in his life and hinted that he needed to rest and if need be return to the United Kingdom for further check-ups.
"He also said that the president's two years in office had been "eventful and fruitful".
Before he departed, the President assured that there was no cause for anxiety concerning the ship of state, saying that Vice-President Yemi Osinbajo will take charge of government in his absence.
Earlier on Sunday, he was pictured sitting in an armchair at his residence, dressed in white traditional robes, looking gaunt, surrounded by 82 recently released Chibok schoolgirls.
A senior advocate of Nigeria, Mr. Ahmed Raji (SAN), told LEADERSHIP that since it is an administrative issue, the panel has to wait for the president to return from his trip.
