ABUJA, May 13 (Reuters) - Nigeria's President Muhammadu
Buhari appointed Ibrahim Gambari as his new chief of staff,
secretary to the government said on Wednesday.
Gambari was Nigeria's minister for external affairs during
Buhari's military regime from 1984 to 1985, and later became an
under-secretary-general at the United Nations.
He replaces Abba Kyari, who died last month after
contracting the coronavirus and was one of the most powerful men
in Nigeria, acting as a gatekeeper to the president.
