New pictures have emerged of Nigeria's ailing President Muhammadu Buhari for the first time since he left the country on medical leave 80 days ago.
President Buhari has been battling an undisclosed illness since the start of the year and has spent long periods out of the country receiving treatment in the UK.
On Sunday, his aides released a photo of the President having lunch with senior member of his ruling party, All Progressives Congress (APC) in London.
