Chief of staff to President Muhammadu Buhari, Abba Kyari, has passed away after a long battle with coronavirus.

The presidency disclosed this in a tweet in the early hours of Saturday.

It would recalled that Kyari had, upon his return from a trip to Germany, tested positive for coronavirus tested positive for coronavirus and thus gone on self-isolation in late March.

He was subsequently moved to Lagos for treatment. Details of his death are still grey but Femi Adesina, presidential spokesman, confirmed it in a tweet.

“Chief of Staff to the President, Mallam Abba Kyari, passes on. May God rest his soul. Amen. Funeral arrangements to be announced soon” he tweeted.

Aside from being the chief of staff to the president, Kyari is also the president’s henchman.

Abba Kyari is considered by many as the most important member of Buhari’s cabinet so much so that many regarded him as the de facto president, the unseen brain behind all Buhari’s government policies and decisions.
