Buhari has been gone for months. The last Nigerian president absent this long died in office.

Nigerian President Muhammadu Buhari has been out of the country since May 7, seeking medical care in London. He has not disclosed the nature of his condition, and official updates about him have been rare.

It was only last week that the government released a photo of Buhari, the first image of him since he left Nigeria. This is Buhari’s second medical leave to the United Kingdom this year; his previous trip was nearly two-months long.
