Despite still receiving medical treatment for an undisclosed ailment in London, President Muhammadu Buhari has accepted his nomination as the leader of the “2018 AU theme on the fight against corruption”.

The nomination took place during the 29th session of the Assembly of Heads of States and Governments of the AU in Addis Ababa, Ethiopia on June 4, 2017.

In a statement on Tuesday, Femi Adesina, President Buhari’s Special Assistant on Media and Publicity, also said that the President wrote to Alpha Conde, the President of Guinea, for “the nationwide prayers held last week by Guineans for his quick recovery and good health”.

“I thank you for your kind and thoughtful action in organizing nationwide prayers for my good health,” Buhari said in the letter to Conde who is also the current Chairman of the Assemblies of Heads of States and Government of the AU.

“Your Excellency will be pleased to hear that I am making good progress and as soon as doctors advise, I shall return to my duties and continue serving the Nigerian people who elected me and are daily praying for my recovery.”

President Buhari expressed his readiness to accept the new AU responsibility “and to reiterate my commitment to contribute towards our collective efforts to strengthen good governance and development on the continent”.

“I therefore look forward to working closely with you in the realization of this objective,” the letter read.

Buhari has been in the UK since the past 79 days.
