On 27 August 2015 Nigeria’s President Muhammadu Buhari appointed former United Bank for Africa chief Alhaji Abba Kyari his new chief of staff, as part of his first senior government appointments since taking office.
Kyari, who has degrees in law and sociology from Cambridge and Warwick universities in the United Kingdom, has held a number of roles in the private sector, including at Unilever and Mobil.
The chief of staff is a non-ministerial role but its holder is typically an important fixer and influential presidential aide.
The role of government secretary went to Babachir David Lawal, an engineer with experience in telecoms, whereas retired Colonel Hameed Ibrahim Ali becomes head of the Nigerian Customs Service.
Former lawmakers Ita Enang and Suleiman Kawu were appointed as advisers on parliament while the Nigerian Immigration Service is to be headed by Kure Martin.
Buhari came to power on 29 May 2015, vowing to crush Boko Haram, the Islamist insurgency in the northeast, and crack down on endemic corruption.
