Nigerian Vice President Goodluck Jonathan says the country's ailing president will return to Nigeria soon.
The vice president, speaking in Abuja, did not indicate when President Umaru Yar'Adua is expected back.
Mr. Yar'Adua left Nigeria in late November, when he traveled to a Saudi hospital to be treated for a heart condition. He also suffers from a chronic kidney ailment.
On Wednesday, Nigeria's cabinet and Senate made conflicting statements on whether Mr. Yar'Adua is fit to remain in office.
The cabinet, appointed by the president, ruled that Mr. Yar'Adua is capable of performing his duties.
The Senate said Mr. Yar'Adua should formally notify the National Assembly of what it called his "medical vacation." The constitution says if such notification is given, the vice president must take over temporarily.
