Nigeria President Muhammadu Buhari leaves the capital Abuja today for a four-day medical trip to the United Kingdom – his fourth since he came to power in 2015.
Mr Buhari, who arrived back from a visit to the United States last week, announced the trip on Twitter on Monday evening.
I will be traveling to the United Kingdom tomorrow, to see my doctor, at his request. Will be away for four days; back in Abuja on Saturday, May 12.

It is not known what the president is suffering from, and the announcement is sure to raise questions among opposition figures.
However, last year he spent 104 days in the UK. He also met his doctor last week during a stopover to refuel in London on the way back from the US.
