LAGOS, Aug. 19 (Xinhua) -- Nigerian President Muhammadu Buhari will arrive in Abuja, capital of Nigeria, on Saturday, after receiving medical attention in London, a statement from the presidency said.

Presidential spokesperson Femi Adesina said the Nigerian leader is expected to speak to citizens in a broadcast by 7 a.m. Monday.

The president left the country on May 7 after handing over power to Vice President Yemi Osinbajo, who has functioned as acting president since then.

The Nigerian leader received the latest medical attention two months after his return from a similar medical vacation, the same day he received 82 Chibok Girls freed by Boko Haram.

While in London, Buhari was visited by a number of Nigerian officials, beginning with the vice-president, who first hinted Nigerians about the president's massive recovery.

Buhari had also told his visitors that there was tremendous improvement in his health, but he has learned to obey doctor's orders, rather than be the one issuing the orders.

"I feel I could go home, but the doctors are in charge. I've now learned to obey orders, rather than be obeyed," he told his visiting media team.
