Nigerian president's wife may not back him at next election

The wife of Nigerian President Muhammadu Buhari says she may not back her husband at the next election unless he shakes up his government. Aisha Buhari, who has never held political office but joined her husband on the campaign trail last year, told the BBC in a interview published on Friday that her husband did not know most of the officials he had appointed, and that many owed their positions to the influence of "a few people".
