The president will leave the country with three state governors and cabinet ministers on Sunday.
This was disclosed in a press statement signed by the president's Special Assistant on Media and Publicity, Femi Adesina, on Friday, September 15.
Adesina said the president will meet with his US counterpart, President Donald Trump, and other world leaders during the session where the welcoming reception will be hosted by the UN Secretary General, Antonio Guterres.
He also said the president will pass through London on his way back to the country, a move that's bound to raise eyebrows.
President Buhari will travel with Governor Abdulaziz Yari of Zamfara state, Governor Dave Umahi of Ebonyi state, Governor Rotimi Akeredolu of Ondo state, and other key members of his cabinet.
