A year on from Nigerian election victory, Buhari's reforms flounder

By Julia Payne and Ulf Laessing ABUJA (Reuters) - Almost a year after winning an election on promises to fix Nigeria, Muhammadu Buhari's grand vision of reform is fading, with power centralised in his increasingly remote presidency and the bureaucracy in disarray. Power is concentrated in Buhari's office, where files pile up on the desk of his chief of staff. Ministers appointed only in November - more than six months after Buhari's victory - are reluctant to make decisions, diplomats say.
