They are called the 'Concerned Nigerians' group and they have threatened to take to the streets if they do not see the president and hear him speak.

The group issued the threat in a statement signed by its convener, Deji Adeyanju and Secretary, John Danfulani.

The group also called on the Senate President, Bukola Saraki and the Acting President, Yemi Osinbajo to set up a medical panel to ascertain whether Buhari is incapacitated or not.

The group anchored its demand on Section 144 sub-section 4 of the Nigerian Constitution.

The statement reads, “If the President is found with any infirmity that renders him incapable of discharging his duties, the Senate President and the Speaker of the House of Representatives shall officially declare him incapable of discharging his duties and declare his office vacant as prescribed in subsection 2 of section 143.

“To this end, we urge President Buhari to address the nation via a live video on or before the 60th day (2 days from today) of his absence.

It further demanded that representatives of some media outfits be present at the live event.

“In failing to do so, we will begin a series of peaceful processions and mass action across the country in Abuja, Lagos, Port Harcourt and Kaduna and also outside the country in London and New York

"The protests are aimed at sensitizing the public as to the legal & constitutional crisis created by President Buhari’s continued absence from office and the insistence of the cabal to shield him away from his constituents, the Nigerian people.”

Buhari has been away on medical vacation in the United Kingdom since May 7 treating a strange and closely hidden ailment.
