ABUJA, Feb 24 (Reuters) - Nigeria's Acting President Goodluck Jonathan will continue to run state affairs while President Umaru Yar'Adua recovers after three months of medical treatment in Saudi Arabia, the presidency said on Wednesday.

"President Yar'Adua wishes to re-assure all Nigerians that on account of their unceasing prayers and by the special grace of God, his health has greatly improved," Yar'Adua's spokesman Olusegun Adeniyi said in a statement.

"However, while the President completes his recuperation, Vice President Jonathan will continue to oversee the affairs of state," the statement said.
