In recent months, President Buhari has visited many of Nigeria’s trouble spots, including the north-eastern town of Dapchi, where 110 schoolgirls were abducted in February by militant Islamist group Boko Haram.
He also visited the middle belt states of Taraba, Plateau and Benue, which have been hit by clashes over grazing land between nomadic herdsmen and farmers.
These visits can now be seen as an effort to demonstrate a hands-on approach in dealing with some of the main challenges facing Nigeria as he seeks re-election.
But doubts remain about Mr Buhari’s health after he made three trips to the UK last year to seek treatment. Buhari will be seeking a second term in office in elections due next year. It ends months of speculation about whether the 74-year-old leader plans to run for re-election.
His first term has been beset by poor health, which saw him spend months in the UK last year receiving treatment and this is exactly the point with BBC and other foreign media houses are concerned with.
